mPower POLI MP400 Diffusion 4-Gas Detector LEL/O2-LF/H2S/CO
3 Year Warranty


The mPower Electronics POLI MP400 Diffusion 4-Gas Detector is a basic 4-gas model with diffusion sampling, configured with oxygen lead free (O2-LF), LEL, carbon monoxide (CO) and Hydrogen Sulfide (H2S) for confined space entry compliance. With 4 sensor slots the use of combination sensors allows up to 6 gases to be measured. Contact us at 800-829-9580 for larger wireless systems with up to 32 monitors. Smart sensors carry calibration and ID information with them for quick exchange in the field during Hazmat response. The MP400 has rugged construction and easy-to-learn 2-button operation. The unique Man-Down alarm feature notifies team workers wirelessly if a user becomes incapacitated.

Applications: Industrial hygiene, Oil and gas, Fire ground "Toxic Twins" detection, Environmental, Chemical, Pharmaceutical, Telecommunications
