Description


High Temperature Humidity Transmitter Upto 200°C with LED Display for Textile Printing and Dyeing
The DB441 transmitter consists of two-channel LED display for the exact measurement of humidity and temperature with ranges from 0 to 100 % RH and -40 to 200℃. It is used for measuring relative humidity, absolute humidity, temperature, volume ratio, mixing ratio and dew point. Equipped with an aluminum enclosure and a 316L stainless steel probe, the DB441 transmitter is pressure and corrosion resistant and applied in the tough industrial environments such as textile printing and dyeing, shaping and drying, papermaking, drying boxes, environmental chambers, hydrogen fuel cells etc industries.

The DB441 series transmitter is available in different installation modes: duct directly or wall-mounted with an extra probe.
