The POLI multi-gas detectors (MP400 & MP400P) offer 4- or 5-gas monitoring of oxygen (O2), combustible (LEL) gases, toxic gases, carbon dioxide (CO2), and volatile organic compounds (VOCs). The MP400 is a diffusion sampling model with standard O2, LEL, carbon monoxide (CO) and hydrogen sulfide (H2S) configuration. A firefighter version uses O2, LEL, CO and hydrogen cyanide (HCN) sensors, and a 5-gas version including sulfur dioxide (SO2) is also available. The MP400P is a standard model with pump and allows a full selection of sensors, e.g. over 30 different electrochemical (EC) sensors, pellistor for LEL, non-dispersive infrared (NDIR) for hydrocarbons in both %LEL and %Vol ranges and photo-ionization detector (PID) for VOCs. The MP400S is an advanced model with pump and a built-in wireless module that sends critical data including panic, man-down, gas concentration, and battery alarms to supervisors and control centers on site or at remote locations for faster responses and maximized safety. The MP400S is used in concert with a head monitor MP400H for teams of up to 8 monitors in an mSquad are up to 64 monitors in an mPlatoon system. This User Guide covers the basic operation of the individual MP400S and MP400H instruments; for information on setting up and operating systems of multiple instruments, see the mSquad User's Guide
