Description
Overview
GAOTek nh3 single gas detector lcd offers a simple, personal protection for a wide array of toxic gas and oxygen (02) measurement applications. In addition to common sensors such as carbon monoxide (CO), hydrogen sulphide (H2S), nitrogen dioxide (NO), ammonia (NH3) and sulphur dioxide (S02), we offer less-common sensors including chlorine (C12), chlorine dioxide (C102), phosgene (COC12), hydrogen chloride (HCl), arsine (AsH3), phosphine (PH3), ozone (03), methyl mercaptan and ethylene oxide. It comes up with long-life lead-free sensors or with inverted alarms for inert gas applications. The monitors have a large LCD providing maximum readability in the field and are made with six bright red LEDs allowing for quick alarm notification. Constructed of strong and durable material, it is designed to be comfortable, yet drop-resistant. It can easily be bump tested and calibrated with the mPower CaliCase System.
