The POLI multi-gas detectors (MP400/MP400P/MP400S/MP400H) offer 4- or 5-gas monitoring of oxygen (O2), combustibles (LEL), numerous toxic gas options, carbon dioxide (CO2), and volatile organic compounds (VOCs). The MP400 is a basic 4-gas model with diffusion sampling, often configured with O2, LEL, carbon monoxide (CO) and Hydrogen Sulfide (H2S) for confined space entry compliance. The MP400P has pumped sampling and offers a full range of over 30 sensor options, including electrochemical (EC), pellistor, non-dispersive infrared (NDIR) and photo-ionization detector (PID). With 4 sensor slots the use of combination sensors allows up to 6 gases to be measured. The MP400S and MP400H are used in wireless communication systems for real-time monitoring of gas readings and alarm status, including man-down alarm, from remote locations for better visibility and faster response. One MP400H head monitor communicates with up to 7 MP400S Soldiers. Contact us for larger wireless systems with up to 32 monitors
