Overview
Enviro Test Construct durable ammonia gas detection and alarm device is an advanced detection instrument with fall alarm function. OLED display screen, apply to wide temperature, visible under sunlight. The shell is designed with rubber coated (plastic could which has good waterproof performance. The use of anti-static materials can meet the explosion-proof requirements. It can continuously detect the concentration of toxic gas or oxygen in the ambient air of industrial and mining enterprises, with sensitive reaction and convenient carrying. It has been widely used in iron and steel metallurgy, petrochemical industry, emergency rescue, industrial safety and other Industries.
