Bacharach Toxic and Combustible Gas Detector 6300 Series

Bacharach Toxic and Combustible Gas Detector


The Bacharach 6300 Series or MGS-150 Gas Detector is a standalone micro-processor-based system for continuous, effective monitoring of toxic and combustible gases. The 6300 Series provides a 4-20 mA output in proportion to the level of gas present and relay output to activate additional horns, strobes, or ventilation systems. The modular design adds functionality. The unit features a built-in 85 dBA buzzer. the rugged polycarbonate housing is resistant to rust, corrosion, and dents. The 6300 Series Gas Detector is designed to be used as part of a control system that helps to prevent the formation of a hazardous environment when properly installed and maintained.
