JT2011 – WBGT Index Meter – Beijing JT Technology Co., Ltd

Separate design of the sensor group and the body, easy to replace the sensor group
Built-in relative humidity sensor, real-time measurement of air relative humidity
LCD screen with backlight, easy to read
Sturdy integrated body, with certain dustproof, waterproof, anti-drop functions
3 expandable sensor channels for fast gradient measurement
Interchangeable 50mm and 150mm black balls for a variety of occasions Chinese/English dual language menu options
Users can calibrate the sensor by themselves with the calibration device
Optional water-filling type (JT2011) and water-free type (JT2013) two specifications
The ISO standard and GBZ/T 189.7-2007 pointed out: when the heating is uneven, the WBGT measurement should be performed on the head, abdomen, and feet at the same time, and the average value is used to calculate the WBGT. The calculation formula is: WBGT=[

WBGT (head) + 2xWBGT ( abdomen) +WBGT(feet)] / 4
Expandable 4G wireless transmission, view historical data through the cloud platform
Optional 4G wireless transmission module, real-time view measurement data through the JT cloud platform, you can also download historical data within one year
The supporting software of JT2011 can provide users with data downloads, curves Drawing, report issuance, etc.
The software has built-in multiple standard algorithms and is applicable to commonly used standards around the world
JT2011/JT2013 two specifications
JT2011 is water-added wet bulb temperature, the wet bulb temperature result is the measured value
JT2013 is the water-less type wet bulb temperature, the wet bulb temperature value is the calculated value (suitable for long-term unattended indoor measurement) without adding
water The temperature error of the wet bulb is about ±1°C (indoor measurement).
It is recommended to use JT2011 outdoors or in an environment with ambient wind, and JT2013 is not suitable for windy environments.
