Large Digital WBGT Display (Heat Stress Index)

  • Heat stroke prevention
  • Large display for WBGT index and Temperature
  • Effective way to make awareness of heat stroke during Summer time sport and high temperature working environment like construction field, house cultivation, etc.
  • Measuring WBGT index at indoor and outdoor
  • RED LED indication and easy to read from far way. (visible distance approx.10m)
  • Display board and sensor can be separated. (Distance between display and sensor parts : up to 100 m)
  • The tripod stand is available for easy installation and moving.
  • Output of measured WBGT index data can be saved in computer easily.
  • Remote monitoring of field like gymnasium, playing grounds etc. can be done from the staff room.
Display range WBGT 0 to 60°C
Surrounding Temperature 0 to 60.0°C
Relative humidity 10 to 90% RH
Glove bulb temperature 0 to 80°C
Measuring accuracy WBGT index +/- 1.5°C (10 to 40°C)
Surrounding temperature +/- 0.5°C (20 to 50°C)
Relative humidity +/- 3% RH (30 to 90% RH, at 25°C)
Glove bulb temperature +/- 0.5°C (20 to 60°C)
WBGT calculation - Without solar load WBGT=0.7×Tnw + 0.3×Tg
- With solar load WBGT=0.7×Tnw + 0.2×Tg + 0.1×Ta
