The POLI multi-gas detectors offer 4- or 5-gas monitoring of toxic gases, oxygen (O2), combustibles (LEL), carbon dioxide (CO2), and volatile organic compounds (VOCs).

The POLI multi-gas detectors offer 4- or 5-gas monitoring of toxic gases, oxygen (O2), combustibles (LEL), carbon dioxide (CO2), and volatile organic compounds (VOCs).

The POLI with a pump is an advanced model with a built-in pump that allows a full selection of sensors for a wide range of applications, including Confined Space Entry, while the POLI is a basic, 4-gas diffusion detector for worker safety at hazardous locations. Smart sensors carry calibration and ID information with them for quick exchange in the field during Hazmat response. The pumped version POLI has rugged construction and easy-to-learn 2-button operation. The unique Man-Down alarm feature notifies nearby workers if the user becomes incapacitated.
