    Description

    POLI Multi-Gas Detectors

    Professional gas detection and alarm systems

    The POLI Multi-Gas Detector Series from mPower Electronics delivers versatile and rugged 4- and 5-gas detection, offering real-time protection in confined spaces, industrial environments, and emergency response scenarios. The MP400 is a reliable diffusion-based 4-gas monitor, commonly configured with O₂, LEL, CO, and H₂S for OSHA-compliant confined space entry. The MP400P expands capabilities with pumped sampling and supports over 30 interchangeable sensors, including electrochemical (EC), pellistor, NDIR (non-dispersive infrared), and PID (photo-ionization detector) for VOC monitoring.

    With 4 sensor slots and dual or combination sensors, the MP400P can monitor up to 6 gases simultaneously. For advanced connectivity, the MP400S and MP400H models offer wireless communication for centralized data monitoring and remote response. The MP400H serves as a head unit, linking with up to 7 MP400S field units for real-time gas readings, alarm status, and man-down alerts—ideal for coordinated operations and rapid intervention.
