• Meter accurately determines the Heat Stress level by factoring a combination of humidity, temperature, air movement, and direct solar radiation
• Uses a capacitance sensor to accurately measure Wet Bulb Globe Temperature (WBGT), Black Globe Temperature (TG), Relative Humidity (%RH), Air Temperature (TA), Wet Bulb (WT) and Dew Point (DEW)
• Black Globe Temperature (TG) monitors the effects of direct solar radiation on an exposed surface
• In/Out function displays the WBGT value with or without direct sun exposure

 

• Built-in sensors measure Air Velocity, Air Flow, Temperature, Humidity, Wet Bulb, Dew Point, Heat Index, Wind Chill, Barometric Pressure, Altitude, and UV Light
• Field replaceable low friction vane wheel improves air velocity accuracy

• Data Hold, Auto Power Off
• Complete with built-in multiparameter sensors, wrist strap, and CR2032 battery

 

• Tests for faulty wiring in 3-wire receptacles: Correct, Open Ground, Open Neutral, Open Hot, Hot/Ground Reverse, Hot/Neutral Reverse
• Lights indicate circuit condition
• Standard North American 3-prong plug

 

• True RMS for accurate AC measurements
• 6000 count backlit LCD display
• Low Impedance (LoZ) prevents false reading caused by ghost voltages
• Low Pass Filter (LPF) for accurate measurements of variable frequency drive signals
