The UNI Single Gas Detector, MP100 offers a simple, personal protection for a wide array of toxic gas and oxygen measurement applications. In addition to common sensors such as carbon monoxide (CO), hydrogen sulfide (H2S), Nitrogen Dioxide (NO2), Ammonia, (NH3), and Sulfur Dioxide (SO2), mPower offers less common sensors including Chlorine (Cl2), Chlorine Dioxide (ClO2), Hydrogen Fluoride (HF), Phosphine (PH3), Ozone (O3), Methyl Mercaptan and Ethylene Oxide. 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 a strong and durable material, the UNI is designed to be comfortable, yet drop resistant. The UNI series can easily be bump tested and calibrated with the CaliCase System.
