Using Wet Bulb Globe Temperature Meters To Keep Athletes Safe This Summer

Wet Bulb Globe Temperature (WBGT) devices like the WBGT Heat Stress Meter – 800036 from Sper Scientific can help football teams, construction workers, and others who work or train outdoors stay safe while working and training in hot, humid conditions.  Wet bulb globe temperature devices measure heat, humidity, and air flow that can be used to determine how long a practice session can safely be held.  Using the readings that a WBGT meter provides makes it much easier to protect individuals from heat-related illnesses such as dehydration and heat stroke.  Dangerous and even fatal heat-related illnesses can be prevented with proper tracking and measuring of conditions out in the field.

Currently, the standard for the measuring environmental heat stress is the Wet Bulb Globe Temperature (WBGT) index.  Using wet bulb globe temperature equipment like the WBGT Heat Stress Meter – 800036 handheld meter is one way for schools, medical staff, coaches and others to accurately monitor the WBGT index in order to make more informed decisions about practices.  By staying on top of conditions and being aware of when the environment is too unsafe to practice in can help to reduce the number of heat-related illnesses, and can help prevent death and injuries due to overexertion.

Using WBGT equipment makes it easy to know when conditions are unsafe outdoors.  Knowing when players need increased resting periods, hydration breaks or modifications to equipment is critical to keeping individuals safe, and products like the WBGT Heat Stress Meter – 800036 from Sper Scientific can help.

The 800036 is a lightweight , handheld WBGT meter that not only helps to keep players safe when practicing outdoors, but that also helps coaches plan practice sessions around the weather.  When the readings on the meter start getting to high, coaches and administrative staff know that it’s time to give more breaks, reduce practice sessions or even move the practice indoors into an air-conditioned gym when conditions become unsafe.  By staying on top of the situation and always being informed about the conditions that players are training in, schools can help to protect students both on and off the field, with accurate weather information that is both useful and worthwhile.

A heat stress meter from Sper Scientific gives coaches and staff peace of mind that they are tracking the correct information and doing everything possible to keep kids safe when they are out on the practice field this summer.

On The Road Again

The Sper Team hits the road for the first time in 2015.  We are off to Austin Texas!  At first we thought that we would get to go SXSW, but no we were a week late.  We are heading to the National Safety Council Texas Conference and Expo, March 30-31 at the Austin Convention Center (Booth 321).  We may just have to check out the sushi at Uchi or the BBQ at Stubb’s while showing the great people of Texas our outstanding line of Environmental Meters.

At the Texas Safety Show, Sper Scientific will be demonstrating its line of Indoor Air Quality (IAQ) meters and monitors, Environmental meters, and Light & Sound meters.  This is first time that Sper Scientific has exhibited at this event.  Sper Scientific’s focus at this event is to help environmental and safety professionals optimize their processes and to demonstrate its lineup of new and innovative environmental measurement instruments.

Since 1982, Sper Scientific has been a leading supplier of environmental measurement instruments used by science and industry to maintain EPA compliance, meet OSHA regulations, and measure a wide range of environmental parameters. Sper Scientific also offers NIST traceable instrument certification at its headquarters in Scottsdale, Arizona.

Is The Relative Humidity (RH) In Your Office Making You Sick?

During the cold winter months buildings are closed up tighter with less outside air being introduced into the buildings, resulting in an increase in various indoor air pollutants. While such a scenario may have some validity in homes and buildings that do not have mechanical ventilation, the same cannot be said for all buildings.

An Indoor Air Quality expert in the New York area collected and analyzed the air quality data from over 125 different “Class A” commercial buildings located in the Metropolitan New York region over a five year span. For most of these buildings, air quality testing was performed two to four times a year for many common parameters including carbon monoxide (CO), carbon dioxide (CO2), total volatile organic compounds (TVOC’s), temperature and relative humidity (RH). In analyzing the extensive amount of data gathered, more than 18,000 readings for some of the parameters, various averages and trends were computed.

When the data collected in the spring and summer months was compared to that which was collected in the fall and winter months, a number of somewhat surprising discoveries were made. As can be seen in the table below, there was virtually no difference between the average spring/summer and fall/winter concentrations for most of the parameters which were tested for.

Parameter Spring/Summer Fall/Winter Applicable Guideline Limit
CO2 614.5 ppm 619.1 ppm 700 ppm above outdoor levels
CO 1.45 ppm 1.72 ppm 9 ppm
TVOC’s 1.25 mg/m3 1.21 mg/m3
Temp. 73.9 F 74.3 F 74-78 F summer/68-75 F winter

A significant difference in indoor RH levels with regards to the seasons was noticed. In the spring and summer months, RH levels were found to average nearly 42 percent. In the fall and winter months, though, RH levels averaged under 29 percent, with over half of all the readings below 30 percent and levels as low as 9 percent recorded in some buildings. Low RH levels have been reported to increase the incidence of upper respiratory infections (i.e., common colds) and to cause dryness and irritation of the skin. Other symptoms include dry and sore nose and throat, bleeding nose, sinus and tracheal irritation, dry scratchy eyes and inability to wear contact lenses.

Humidifiers can help to alleviate the symptoms resulting from low humidity, although they are rarely recommend if the problem is purely a comfort issue. Humidifiers, if they are not well maintained and the water changed frequently, can present a serious health risk to building occupants. Excess moisture levels, if left unchecked, can result in microbial growth on building materials. In addition, bacteria can proliferate in a humidifier’s water reservoir, resulting in endotoxins, which are present in the outer membrane of the cell wall of Gram-negative bacteria, being introduced into the indoor air. Exposure to low levels of these toxins can cause airway inflammation and cough, while acute exposures to high levels can result in flu-like symptoms. So when you hear that people “have been getting sick more often than usual”, realize that the problem is more likely than not due to low indoor relative humidity levels. Do not, however, automatically assume this is the problem. It is always best to properly monitor the levels of RH in the workplace and make proper decisions based on the results of these measurements.

What is a Digital Refractometer?

There are certain hindrances with using handheld refractometers, the main one being; obtaining an accurate measurement. When using an optical refractometer, one must place their sample on the prism and look through an eyepiece to determine the measurement of an index of refraction.

The use of a digital refractometer eliminates the uncertainty associated with optical refractometers; a digital refractometer uses an LED light to shine through the sample. When a liquid sample is applied to the measuring surface only some of the light is transmitted through the solution and is lost; while the remaining light is reflected onto a linear array of photodiodes creating a shadow line. The refractive index is directly related to the position of the shadow line on the photodiodes. Once the position of the shadow line has been automatically determined by the instrument, the internal software will correlate the position to refractive index, or to another unit of measure related to refractive index, and display a digital readout.

How Do You Measure Dissolved Oxygen (DO) In Harsh Environments?

Shrimp farmers work in very adverse conditions that impact the chemical make-up of the grow-out ponds. For example, Guatemala is experiencing a drought that has caused what is referred to as the “Child’s Effect” in the shrimp industry. The Child’s Effect causes high temperatures, and increased salinity in the grow-out ponds.

Some of these farmers have turned to Sper Scientific to provide rugged, reliable, and accurate field measurement instruments to help them monitor these harsh conditions. They selected the AquaShock ® DO meter (850046K) and the Sper Scientific Optical Salt Refractometer (300006), which are ideally suited for these severe conditions.

farmerThe farmer in this picture has almost 8,500 pounds of shrimp in a 3,500 square meter pond. They grow shrimp in an artificial ponds like the one behind him in the picture. The water in these grow-out ponds is a combination of sweet water and sea water. This shrimp farmer’s business is located in the southern part of Guatemalan Republic, in Escuintla, in a part called “Monterrico”.

According to the shrimp farmer, measuring the oxygen levels in the ponds, especially at night is critical. The oxygen levels typically fall during the night. If the oxygen level is to low they aerate the water in the ponds to increase the oxygen level.

This shrimp farmer selected the AquaShock® DO meter because it is designed and was tested to ensure accurate, reliable water quality measurement under any conditions. Results are easy to read, in any light, on the large LED backlit display. The AquaShock® is powered by a long-lasting, environmentally friendly, rechargeable Lithium-Ion battery, which allows the farmer to spend his time managing his shrimp and not worrying about his meter. The other feature the farmer enjoys about the AquaShock® DO meter is that it is very intuitive and includes all the functions he will likely ever need, including: review of 99 memories (min/max/ave) directly on the meter’s display, internal clock and calendar, temperature in °C or °F, auto-ranging, automatic and manual temperature compensation, and hold.

Sper Scientific offers two different optical salt refractometers. The 300006 salt refractometer has a range of 0 ~ 28%. The 300011 salt refractometer has a range of 0-100ppt and comes with Automatic Temperature Compensation (ATC). Both of these optical refractometers would be ideal for this application. The shrimp farmer did not require ATC, which is why he selected the 300006 for his farm.
