Multi-gas detector POLI

hydrogen sulfideH2Soxygen

Overview
Uniphos is a distributor of POLI multi-gas detectors. The POLI detectors are available in three main versions (MP400, MP400P and MP400S) and provide 4- or 5-gas monitoring for oxygen (O2), combustibles (LEL), carbon monoxide (CO), hydrogen sulfide (H2S) and optional sensors for carbon dioxide (CO2), volatile organic compounds (VOCs) and other toxic gases. Devices are offered in diffusion and pumped configurations to support confined-space entry applications.

Models

• MP400: Basic model in diffusion or pumped versions suitable for confined-space gas monitoring.
• MP400P: Basic model similar to MP400, available in diffusion or pumped versions for confined-space compliance.
• MP400S: Pumped model with the widest sensor selection; supports combined CO/H2S sensor for up to five-gas monitoring.

Features

• 4- or 5-gas configurable monitoring (O2, LEL, CO, H2S; optional CO2, VOCs, other toxics).
• Sensor options: electrochemical, pellistor (catalytic), NDIR for CO2 and PID for VOCs.
• Diffusion and pumped (aspirated) versions to match application and regulatory requirements.
• Combined CO/H2S sensor option to enable simultaneous monitoring with a single module.
• Optional wireless communications for real-time remote monitoring and alarm/status reporting, including man-down alerts.
