POLI Multi-Gas DetectorsPOLI Multi-Gas Detectors

Professional gas detection and alarm systems

The POLI multi-gas detectors (MP400/MP400P/MP400S) offer 4- or 5-gas monitoring of oxygen (O2), combustibles (LEL), toxic gases, carbon dioxide (CO2), and volatile organic compounds (VOCs). The MP400 and MP400P are basic models with O2, LEL, carbon monoxide (CO) and hydrogen sulfide (H2S) configuration in both diffusion or pumped versions, for confined space entry compliance. The MP400S adopts a full range of sensor selection, e.g. electrochemical (EC), pellistor, non-dispersive infrared (NDIR) and photo-ionization detector (PID) in a pumped model. Use of a combined CO/H2S sensor in the MP400S allows up to five gases to be monitored. An option of wireless communication enables real-time monitoring of gas readings and alarm status including man down alarm from remote locations for better visibility and faster response.
