product name: Ammonia gas alarm
product brand: Skyeaglee
Product number: SK-600-NH3
Measurement object: Ammonia in the air
product description

Product introduction:

Ammonia, NH3, colorless gas, has a strong irritating odor. The pungent odor of ammonia is a reliable warning signal of harmful concentrations, but due to olfactory fatigue, low levels of ammonia can be difficult to detect after prolonged exposure. Inhalation is the main route of exposure to ammonia. Low concentrations of ammonia can quickly irritate the eyes and moist skin. High levels of ammonia on wet skin or eyes can cause severe chemical burns.

SK-600-NH3 is an explosion-proof and fixed gas alarm with national patent license. It adopts intelligent digital electrochemical sensor monitoring technology and is widely used in chemical, light industry, fertilizer, pharmaceutical, synthetic fiber and other fields.

The product uses original imported sensors, and adopts intelligent processing platform and electrochemical detection technology. It has excellent stability and strong anti-interference ability. The smallest volume in the world, fast response speed and high measurement accuracy! Infrared remote control, safe and convenient to set the alarm without opening the cover. Three-wire system 4-20mA standard current output, perfectly connected to control instruments and DCS, PLC systems.

Precautions:

Corrosion-resistant work clothes, alkali-proof gloves, glasses, rubber shoes, and gas masks should be selected for work, and gas masks should be checked regularly to prevent failure.

Before entering the ammonia working environment, workers should undergo pre-operation physical examination. People with severe chronic bronchitis, bronchiectasis, asthma, and coronary heart disease should not engage in related work.

③ When using ammonia water, keep clean water with you, just in case; during transportation of ammonia water, you should have 3% boric acid solution for emergency flushing; when preparing a certain concentration of ammonia water, you should wear goggles; use When using ammonia water, the operator should be in an upwind position to prevent ammonia from irritating the face. It is forbidden to rub the eyes with hands during operation, and wash hands after operation.
