JT2011/2013 Wet bulb Black bulb Temperature (WBGT) Index Meter

WBGT is composed of three temperature components: black sphere, natural wet sphere, and dry sphere. It comprehensively considers four factors: air temperature, wind speed, air humidity, and radiant heat. JT2011 and JT2013 are independently developed high-precision thermal index testing instruments that can simultaneously test air temperature, self wetting bulb temperature, and radiation temperature. The digital temperature sensor selected for this tester is used as the temperature acquisition end, equipped with our company's independently developed standard 50mm and 150mm radiation black balls, which fully comply with ISO and relevant national standards and can be verified by the National Institute of Metrology.

JT2011 uses a conventional water added wet bulb temperature sensor to directly measure the wet bulb temperature, while JT2013 uses a water free wet bulb temperature sensor to ensure long-term online measurement without worrying about insufficient water for wet bulb temperature. Both models of instruments have built-in relative humidity sensors that can display the relative humidity of the air in real time, and can be configured with 50mm or 150mm black sphere to meet the testing needs of different usage scenarios. The 485 communication interface can easily connect to your industrial control equipment or control device, and can also download and export measurement data through this interface.
