Summary:

Ammonia gas alarms are divided into fixed and portable. Portable ammonia gas alarms are easy to carry and can be turned on at any time to detect ammonia gas concentration. Fixed ammonia gas alarms are composed of two parts: gas detector and gas controller. The detection of ammonia concentration is realized through electrochemical NH3 gas sensor. The gas alarm controller is installed in the duty room and other places where there are people and easy to observe, and receives the ammonia concentration detected by the gas detector, and realizes the display of the concentration and the sound and light alarm function after exceeding the standard, and linkage with external equipment (solenoid valve, exhaust fan, etc.).

Both portable and fixed ammonia alarms have a core component inside, that is, the NH3 gas sensor. At present, in the application of gas sensor detection, the use of ammonia sensor components for detection is a kind of sensor detection method with relatively wide demand and application. In simple terms, the working principle of ammonia gas sensor is to obtain the content value of the measured gas by measuring the induced current through electrochemical reaction.

Product Introduction:

JXCT electrochemical ammonia sensor (NH3 sensor) has a very high sensitivity to ammonia and can detect ammonia in the air at a concentration as low as 30ppm. It is an ideal ammonia sensor and can also be used for ammonia leak detection in the agricultural field.

Ammonia sensor characteristics:

1. Electrochemical principle

2. The range is 0~ 100ppm or 0~1000ppm

3. Linear output

4. High sensitivity to ammonia;

5. Simple circuit in later stage;

6. Strong resistance to environment;

7. Short response time to low concentration ammonia;

NH3 gas sensor mainly detects and shows the concentration of ammonia gas. This kind of gas alarm adopts microprocessor as the control unit and has high performance electrochemical detection sensor with high sensitivity and fast response speed. When the concentration of ammonia gas exceeds normal, the alarm sound will be sent out in time, which is mainly composed of gas alarm controller and gas alarm detector. The products are widely used in metallurgy, petroleum, petrochemical, chemical, light industry, coking, municipal, gas, pharmaceutical, sewage treatment and many special industries and fields.

Function:

Anyhow, ammonia gas is a useful and risk coexist, although it has important use in many fields, but it has the biological toxicity of is already confirmed by scientific research institute, it is undoubtedly another health problems facing humanity, the influence of ammonia is bad for the environment and more should be seriously rise, with the constant change of gas sensor technology, New applications and new requirements are bound to proliferate. Thus supporting the gas sensor industry forward, and to bring users more environmental protection, safety, health, convenience, novel, valuable use experience, so as to benefit the public.
