Introduction
| WBGT is composed of black ball, natural wet ball and dry ball. It takes air temperature, wind speed, air humidity and radiation heat in o account. ped high-precision thermal index measuring instruments of MEWOI, which can simultaneously test air temperature, self-wetting bulb temperature and radiation temperature. This tester uses the most advanced digital temperature sensor as the temperature acquisition terminal. It is equipped with the standard of 50mm and 150mm radiation black sphere developed by our company. It fully meets the ISO, relevant national standards and can pass the verification of the National Institute of Metrology. MEWOI-WBGT2019A uses conventional water-adding wet-bulb temperature sensor to directly measure wet-bulb temperature. MEWOI-WBGT2019B uses none-water wet-bulb temperature sensor to ensure long-term on-line measurement without worrying about the shortage of water in wet-bulb temperature. Both types of instruments have built-in relative humidity sensors, which can display the relative humidity of air in real time and can be configured with 50mm or 150 mm black sphere to ensure the test requirements of different use scenarios. 485 communication interface can more easily access your industrial control equipment or control devices, also can be used to download and export measurement data. |
Functions
1.The split design between sensor group and the fuselage are easy to replace the sensor group. |
2.Internal relative humidity sensor for real-time measurement of relative humidity of air |
3.LCD display with backlight is easy for users to read. |
4.Solid integrated fuselage has a certain function of dustproof, waterproof and anti-falling. |
5.3 scalable sensor channels for fast gradient measurement. |
6.Replaceable 50mm and 150mm black spheres are suitable for many occasions. |
7.The user can calibrate the sensor automatically by using the calibration device. |
8.Optional water adding (MEWOI-WBGT2019A) and no water (MEWOI-WBGT2019B) two specifications. |
