The POLI multi-gas detectors offer 4 or 5-gas monitoring of Oxgen (O2), combustibles (LEL), toxic, Carbon Dioxide (C02) and volatie organic vapors (VOCs). The MP400 and MP400P are basic models of O2, LEL , Carbon Monoxide (CO) and Hydrogen Sulphide (H2S) configuration in diffusion- and pump for compliance application. The MP400S adopts a full range of sensor selection, e.g. electrochemical (EC), pellistor, non-dispersive infrared (NDIR) and photo-ionization detector (PID) in pump. 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.

• Available in diffusion or pumped version
• Man Down Alarm with real-time remote wireless notification
• IP-65 (pumped versions) and IP-67 (diffusion versions)
• With water and dust resistant case
• Real-time gas concentration readings and alarm status enabled by state-of-the-art wireless technology
• Large graphical display icon-driven user interface through intuitive, simple-to-operate two-button user interface
• Easy access to pump, sensor, filter and battery
• Over 30 interchangeable sensor options, including PID for VOC, NDIR and catalytic for combustibles, and NDIR for CO₂
• Intelligent sensors store calibration data, so they can be swapped in the field
