Click to download:MEWOI-KTR20 WBGT Heat Stress Monitor Meter Specification
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. |
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. |

| Black ball temperature sensor | Measuring range: 20~120℃, accuracy:±0.5℃(20℃~40℃),±0.2℃@50℃~120℃), resolution: 0.1℃(PT1000), Black ball diameter: 150mm | |
| Wet bulb temperature sensor | Type: Cylindrical shape,Outer diameter of probe:6±1mm,Minimum length of probe:30±5mm,Range: 5-60℃, accuracy:±0.5℃, resolution:0.1℃ | |
| The probe should be wrapped with highly absorbent materials, such as cotton gauze. The gauze should be in the shape of a sleeve. The size of the gauze should be set on the probe. Too tight or too loose will affect the reading of the probe. The gauze should be kept clean and tidy. The lower end of the gauze should be hanging in a water tank. The free length of the gauze in the air is 20-30 mm. It should be able to prevent the rise of water temperature caused by radiation heat. | ||
