ZP201 Refrigerant gas detection module
**Product Description
**
ZP201 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 , calibration, calibration, with good consistency and high.
Features
High sensitivity, fast response, strong anti-interference ability, long life, stable operation, factory calibrated, sensor fault self-diagnosis
Application
Used for air conditioning, refrigeration system refrigerant leak detection.

Cautions
-
Please do not put the module in organic solvent (include silica gel and other cementing
compound), painting, medicament, oils and fuels, high concentration gas etc. -
Please do not impact or vibrate the module seriously.
-
Please warm up for 5 min before first use.
-
Please do not use the module related with personal safety.
-
Please do not install the module in the severe convection environment.
-
Please do not put in the module in high concentration organic gas for long time.
-
Please supply the module with requested voltage as manual strictly, if voltage is higher than 5.5V, the module will be destroyed irreversibly.
