EA2-TX-100 online dew point sensor
Date: 2025-07-25Read: 9

Online Dew Point Sensor Product Introduction:

The design concept of Easidew transmitter is simplicity and ease of use, and its integrated features are designed to simplify installation and usage services as much as possible. The transmitter that is set up and calibrated makes dew point measurement as easy as temperature and pressure measurement, and can be directly connected to your air or gas management and control system.

·Two wire power supply circuit connection

·Dew point unit or ppm moisture content unit

·IP66(NEMA 4)

·Excellent sensor protection

·Range -100~+20 ° C

·Working temperature -40~60 ° C

·Fast response speed
