Product Features:

Dew point sensor QMLD-1 New Polymer Thln Film Sensor Technology IP65 Protection grade Stable anti-interference High-precision chip Application Scenario In agriculture, laboratories, industrial manufacturing, large warehouses, etc Domain is one of the indispensable tools The low humidity sensitivity should be more than a hundred times higher than that of ordinary humidity sensitive capacitors. The sensor uses a humidity sensitive capacitive type as the core component,which can sense the moisture content of air in extremely low humidity. After multi-point calibra-tion and temperature correction. it ensures the rellability of testing and has accurate measurement results in various environments, which are then converted into current signal output. Stainless steel probe housing Waterproof and dustproof, resistant to high temperature, corro-sion, good compactness, fast response, low environmental requirements for use, IP65 protection level can provide good protection even in harsh environments.
