Making Powerful Senses


In harsh working conditions where hazardous gases pose a threat to worker safety and health, reliable gas detection and monitoring is key. The POLI Multi-Gas Detector offers advanced gas detection for a wide range of applications and industries.
POLI MP400 – This is the base model POLI Multi-Gas Detector. It is a compact, diffusion-based detector that monitors up to 4 gases simultaneously.
POLI MP400P – This POLI model is equipped with an Inert Gas Mode and allows for custom oxygen alarms.
POLI MP400H & POLI MP400S – These two POLI models work with the mSquad and mPlatoon wireless communication system. The POLI MP400H head monitor communicates with up to 7 POLI MP400S models to create an mSquad. The mSquad can be linked to other mSquads for large-scale operations through a modem to create an mPlatoon.

The POLI Multi-Gas Detector detects oxygen levels, flammable gases, and toxic gases before and during entry. This is essential for workers entering tanks, vaults, and other confined spaces.
These multi-gas detectors monitor volatile organic compounds (VOCs), hydrogen sulfide (H₂S), carbon monoxide (CO), combustibles (LEL), and oxygen (O₂), all of which are important gases to monitor during oil and gas operations. The POLI supports worker safety during drilling, pipeline maintenance, refining, and more.
The POLI MP400P with the Inert function is suitable for oxygen-deficient environments. First responders often also need to detect VOCs during vehicle accidents and industrial fires. The POLI’s fast sensors help assess the scene and determine what safety equipment is needed.
Workers in wastewater treatment facilities often have to monitor for methane (CH₄), hydrogen sulfide (H₂S), ammonia (NH₃), and chlorine (Cl₂). The POLI ensures accurate detection in underground work, treatment tanks, and chemical storage areas.
Because the POLI detects VOCs and combustible gases, it is critical during leak detection and spill response. The detector enhances both safety and regulatory compliance.
The POLI Multi-Gas Detector offers versatility, durability, and reliable gas detection. To learn more about the mPower products and gas detection solutions, contact us through our website here or call us at 1-866-676-9377.
