Module
Application:
Refrigerant leakage detection in air conditioningProduct characteristics:
High sensitivity, fast responseDescription
The TX210-Q201 refrigerant gas detection module utilizes a semiconductor gas sensor manufactured using an advanced multi-layer thick-film manufacturing process. This sensor incorporates a filter adsorption layer to mitigate interference from gases like alcohol, resulting in extremely high sensitivity to refrigerant gases. The module undergoes aging, calibration, and testing to ensure excellent consistency and high sensitivity.
