mPower MUNI MP420
4 In 1 Compact Multi-Gas Detectors
OVERVIEW
The MUNI MP420 is a compact and lightweight 4-gas detector for worker safety in hazardous locations with four standard sensors for oxygen (O2), combustibles (LEL), carbon monoxide (CO), and hydrogen sulfide (H2S). Alternative sensors include low power infrared methane (CH4), sulfur dioxide (SO2) and hydrogen cyanide (HCN). The detector is housed in a rugged enclosure with no moving parts. Its battery power provides 24 hours of operation for a standard 4-gas detector and extended run time when using a low power infrared sensor. Simple 2-button operation provides ultimate ease of use and significantly reduces user training time. To save users money, sensors are not interchangeable and must be specified at the time of purchase.
