Overview
BV312 refrigerant gas detection module adopts advanced multi-layer thick film manufacturing process semiconductor gas sensor element. The gas sensor element contains a filter adsorption layer to reduce the interference of alcohol and other gases, and has extremely high sensitivity to refrigerant gas. The module has been aged , calibrated, with good consistency and high sensitivity.
Key Features
High sensitivity, fast response, strong anti-interference ability, long life, stable operation, factory calibrated, sensor fault self-diagnosis
Applications
Used for air conditioning, refrigeration system refrigerant leak detection.
