Extech HT30 Heat Stress WBGT Meter

Heat Stress WBGT Meter

The Heat Stress WBGT (Wet Bulb Globe Temperature) Meter accurately determines Heat Stress levels — how hot it feels outside — by factoring humidity, temperature, air velocity, and direct solar radiation using the HT30’s Black Globe tip.

Additional Features

Additional features include Auto Power Off with override, and a built-in RS-232 interface with optional Windows-compatible software allows users to compile data on environmental conditions and generate reports.

Why is Heat Index Important?

The National Weather Service devised the “Heat Index” (HI), (sometimes referred to as the “Apparent Temperature”) as a measure of human-perceived equivalent temperature — how hot it really feels in degrees Fahrenheit — when air temperature is factored in with relative humidity. For example, if the air temperature is 95 degrees F and the relative humidity is 65%, it actually feels like it is 119 degrees F.

Applications

Outdoor supervisors and coaches are charged with safeguarding the well-being of their workers and players. This includes monitoring environmental conditions to prevent people from succumbing to the effects of heat stress, especially during outdoor activities taking place from late spring to early fall. To protect the health of their workers and athletes, many supervisors and coaches are monitoring heat, humidity and other environmental factors (including stifling indoor conditions). This is because environments over 80 degrees F combined with high humidity reduce a person’s ability to dissipate heat. Even when environmental conditions may seem safe, temperature and humidity can rise quickly. This is compounded by other factors — overexertion, improper hydration, and heavy gear — that can all take a toll on a person’s health. This is why monitoring environmental conditions is so important.
