Application Support

Product Detail

The POLI multi-gas detectors (MP400/MP400P/ MP400S) offer 4 or 5-gas monitoring of oxgen (O2), combustible (LEL), toxic, carbon dioxide (C02) gases and volatie organic vapors (VOCs). The MP400 and MP 400P are basic models of O2, LEL , carbon monoxide (CO) and hydrogen sulfide (H2S) configuration in diffuson 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 enable 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 pump version
  • Man Down Alarm with real-time remote wireless notification
  • IP-65/67 water and dust resistant case
  • Real-time gas concentration readings and alarm status enabled by state-of-the-art wireless technology
