Taiwan Hengxin Black Ball Temperature Gauge

Taiwan Hengxin black ball thermometer WBGT thermal index meter model: RHA-AZ8778

• Four parameters: WBGT (wet bulb temperature), TG (black bulb temperature), TA (air temperature), and% (relative humidity).

• Sensors are protected

• Black sphere thermometer measures radiation temperature with a diameter of 75mm

• Provides direct measurement of average radiation temperature!

• Buzzer sounding warning, adjustable alarm value setting

• The temperature unit is a switch

• The battery low voltage indicator shows weak power

• Automatic shutdown or no sleep mode to choose from

• The automatic sampling interval is selected from 1 minute to 120 minutes (2 hours)

• Analyzing through RS232 and PC connection

• Data locking, maximum and minimum average measurement

• Dual display: heat index and temperature or dew point/humidity and air temperature

• ℃/℉ switching function

• Low battery display

• Read indoor and outdoor WBGT, WB, DB orGTWaiting for temperature

• Formula (reference)Indoors / Outdoors and no sun
  WBGT = 0.7 x WB + 0.3 x TG
  Outdoors and full sun
  WBGT=0.7xWB+0.2xTG+ 0.1XTA
