Please be noted:

Question: I want to know what is life of electrochemical sensor and it is one time use or not?

Semiconductor gas sensor 5 years min.

Catalytic gas sensor 3 years min.

Electrochemical gas sensor 5 years min.

Yes, they are one time use. When the sensor life is overdue, the user needs to contact us to replace the gas sensor or replace the whole gas detector unit.
