192. Product Introduction
193. 1. Russia comeco Temperature and Humidity Sensor Thin-Film Humidity Sensing Element SH Description:
194. The SH relative humidity sensing element consists of an electrode system on a glass-ceramic substrate, covered with a humidity-sensitive polymer coating and a water-vapor-permeable metal film. This coating system represents a humidity-dependent capacitor. SH uses the capacitance measurement principle to measure relative humidity in air or other non-corrosive gases and gas mixtures, with good long-term stability and linearity, low hysteresis, and good dynamic response.
