Product Overview
The CHR02-2025 series is a high-performance polymer humidity sensor (resistive type) designed for accurate and stable humidity measurement. It features a logarithmic impedance change with relative humidity, driven by the migration of conductive ions within the functional polymer film. This sensor offers excellent sensitivity, long-term stability, and a linear impedance curve comparable to imported sensors, making it a direct replacement for various similar products. It is suitable for a wide range of applications requiring humidity monitoring, including electronic hygrometers, humidifiers, dehumidifiers, and air conditioning systems.
