Please be noted:

Question: What is type of your company sensor of gas alarm/detector? and i want to know that the sensor of KAB KAD, KAC is better than other model or not?

For home use, most of the gas alarm/detector use semi-conductor gas sensor and some use catalytic gas sensor or electrochemical gas sensor. Here is the details:

GN & KAB catalytic gas sensor

KAC & KAD electrochemical gas sensor

The other models semi-conductor gas sensor

Yes, KAB, KAC and KAD are better than the other models, because:

1. They use high-sensitivity gas sensors, so the performance is better.

2. The design and materials are better.

3. They are designed complying with EN50194 or EN50291 standard, which is European standard.

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.
