The UNI MP100 offers a simple, personal protection for a wide array of toxic gas and oxygen (O2) measurement applications. In addition to common sensors such as carbon monoxide (CO), hydrogen sulfide (H2S), nitrogen dioxide (NO2), ammonia (NH3) and sulfur dioxide (SO2), we offer less-common sensors including chlorine (Cl2), chlorine dioxide (ClO2) hydrogen chloride (HCl), 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 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 mPower CaliCase System.
