JT2011 – WBGT Index Meter

Model: JT2011-E2

WBGT is composed of three parts of temperature sensors: wet bulb, black bulb and dry bulb. It comprehensively considers four factors: air temperature, wind speed, air humidity and radiant heat.
JT2011 and JT2013 are high-precision thermal index test instruments independently developed by "JANTYTECH Technology", which can test air temperature, wet bulb temperature and radiation temperature at the same time. This tester adopts the most advanced digital temperature sensor as the temperature acquisition terminal, equipped with the standard 50mm and 150mm radiation black ball independently developed by our company, which fully complies with ISO and relevant national standards, and can pass the verification of the National Institute of Metrology.

Product introduction
  • JT2011 and JT2013 are high-precision thermal index test instruments independently developed by "JANTYTECH", which can test air temperature, wet bulb temperature and radiation temperature at the same time. This tester adopts the most advanced digital temperature sensor as the temperature acquisition terminal, equipped with the standard 50mm and 150mm radiation Globe ball independently developed by our company, which fully complies with ISO and relevant national standards, and can pass the verification of the National Institute of Metrology. JT2011 adopts conventional water-added wet-bulb temperature sensor to directly measure the wet-bulb temperature. JT2013 adopts water-free wet-bulb temperature, The 485 communication interface can be more easily connected to your industrial control equipment or control devices, and can also The download and export of measurement data can be realized through this interface.
Features
  • 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.
