Electrochemical NH3 gas sensor Introduction

Electrochemical NH3 gas sensor is a gas sensor used to detect ammonia gas concentration in the atmosphere. Ammonia gas sensor uses electrochemical gas detection principle, linear current output, signal is easy to handle, high sensitivity. The electrochemical NH3 gas sensor has the characteristics of rapid response, not easy to be interfered with, wide use, easy installation, plug and play, etc. Ammonia electrochemical gas sensor is suitable for the detection of ammonia gas concentration in harsh or various environments.

Ammonia gas sensor

NH3 sensor use

This IoT ammonia sensor is cheap and stable. It is suitable for occasions requiring real-time monitoring and control of ammonia gas, such as agricultural greenhouses, breeding farms, pesticide manufacturing plants, and chemical plants.


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 gas 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?
