FAQ - NH3 sensor

Where should the nh3 sensor location?

The ammonia sensor should be installed in a place where the gas is easy to leak, and it is determined according to the specific gravity of the detected gas relative to the air.


When the specific gravity of the detected gas is greater than the specific gravity of air, the detector should be installed (30-60) cm away from the ground, with the ammonia alarm position facing downwards.

What are the types of ammonia sensors?

Our company provides three types of NH3 sensors according to the different places where customers use them: wall-mounted ammonia sensors, portable ammonia detectors, and fixed ammonia alarms.

Are you a manufacturer? Do you provide customized services?

Yes, we are professional sensor manufacturers and have been engaged in the production and sales of gas detectors for 15 years. We can provide customized services. We have a professional R&D team.

How to calibrate the ammonia sensor?

Our ammonia sensor has been calibrated before leaving the factory, and can be used directly after installation, without the customer’s secondary calibration.

Do you provide customized services?

Yes, we are a manufacturer and can provide you with software or hardware customization.
