Description

High Temperature Humidity Transmitter upto 200°C with Extra Probe in Harsh Environment
DB440 transmitter is designed for fixed installation in industrial applications where conditions are within the range of 0 to 100 % RH and -40 to 200℃ T. The probe can survive exposure to temperature up to 200°C. Equipped with an aluminum enclosure and a 316L probe, This series transmitter is widely used under high temperature environments for measuring relative humidity, absolute humidity, temperature, volume ratio, mixing ratio and dew point in textile printing and dyeing, shaping and drying, papermaking, drying boxes, environmental chambers, hydrogen fuel cells etc industries

The DB440 series transmitter is available in different installation modes: duct directly or wall-mounted with an extra probe.
