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.

The removable SD card is easy to transport and insert into a computer’s memory card slot or SD card reader.


Large display continually monitors temperature, RH & all heat stress indicators: Air Temperature, RH, Heat Stress, Dew Point, Wet Bulb  Continually monitor all heat stress indicators Air Temp and RH. Recalls min/max temperature and provides visual alarms for user selectable hi/lo temperature thresholds. Features an audible temperature alarm, and records up to 32,000 data points that can be downloaded using the USB cable and software that come with the unit.


Monitor up to 12 environmental parameters with one tiny instrument. Light weight, tiny size with simple, one-hand, operation.

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.

It’s Summer Time! Time To Be Aware Of Heat Stress.

Workers who are exposed to extreme heat or work in hot environments may be at risk of heat stress. Exposure to extreme heat can result in occupational illnesses and injuries. Heat stress can result in heat stroke, heat exhaustion, heat cramps, or heat rashes. Heat can also increase the risk of injuries in workers as it may result in sweaty palms, fogged-up safety glasses, and dizziness. Burns may also occur as a result of accidental contact with hot surfaces or steam.

Workers at risk of heat stress include outdoor workers and workers in hot environments such as firefighters, bakery workers, farmers, construction workers, miners, boiler room workers, factory workers, and others. Workers at greater risk of heat stress include those who are 65 years of age or older, are overweight, have heart disease or high blood pressure, or take medications that may be affected by extreme heat.

Prevention of heat stress in workers is important. Employers should monitor their workers environment for heat stress and provide training to workers so they understand what heat stress is, how it affects their health and safety, and how it can be prevented.


Sper Scientific offers several heat stress meters to help employers monitor the conditions of their workforce. Below are just of the temperature monitors that we offer.
