TENMARS TM-188B HEAT STRESS WBGT METER

Specifications

SKU: TENMARS TM-188B HEAT STRESS WBGT METER


 
  • Quick-response capacitance sensor.
  • Accurate measurement for wet bulb globe
  • BLE. wireless transmission


Application

Featuring automatic data recording and BLE. wireless transmission, it can monitor and transmit data in real time to smartphones or tablets via a dedicated app, for in-depth analysis and advanced applications. It is ideal for environments where real-time monitoring is essential, such as sports training facilities, outdoor event venues, and high-temperature workplaces. The system supports faster, more convenient heat hazard monitoring and provides early warning capabilities.
 
In order to measure the WBGT index, you should refer to the following regulations:
  • ISO7243 : Hot environments. Estimation of the heat stress on working man.
  • ISO7726 : Ergonomics of the thermal environment-instruments for measuring physical quantities.
