Description
Overview
GAOTek ammonia gas detector is equipped with the original imported sensors, possessing high sensitivity and reliable stability. It is characterized as its simplicity and convenience, getting rid of replacing battery, dust-proof, and explosion- proof together with low maintenance cost. The upper and lower limit alarm value can be set randomly. It is also equipped with the zero and standard point calibration function, in which  there is the temperature compensation device to minimize the measurement errors with easy maintenance. It is widely used in the place which requires detecting the concentration of the   poisonous and harmful gas, such as oil production, smelting, chemical industry, municipal engineering, sewage treatment, electric power, coal gas mining, tunnel construction, fire control, storage, paper making, pharmacy industry, brewing and the like.
