Description
A resistive humidity sensor, SY-HS-25 Series, is composed of excellent durable resistive sensor and a thermistor for temperature compensation and offers cost competitiveness and convenience for humidity measurement.
This module uses specially consolidated polymer and is designed for industrial environment that includes both temperature environment (-20~85℃) and humidity environment with dew condensation and gases. In addition, it can be used without calibration so that replacement of sensor is easy and convenient.
