Product Overview

HDB440 series high temperature typehumidity transmitterThe temperature and humidity transmitter is designed specifically for demanding industrial applications. The transmitter uses Swiss imported humidity measurement components, which have the characteristics of accurate measurement, wide temperature range adaptability, strong resistance to chemical pollution, stable operation, and long service life. Two 4-20mA current signals are output for temperature and humidity.

The humidity chip used in the HDB440 series has extremely high temperature tolerance and can work for a long time in a high temperature environment of 200 ℃. The special treatment of the sensor surface can enable the sensor to continue working in environments with chemical pollution. It is the best choice for working in high-temperature and harsh environments. widely used inIndustrial site measurement, petrochemical gas emission detection, thermoelectric gas emission detection, tobacco industry, drying oven, environmental testing oven
