Co Monitor

The carbon monoxide (CO) monitor prevents contamination of the air supply by shutting down the compressor when the CO level is too high. The cartridge monitor will do the same when the moisture level is too high. These monitors are available for electric, gasoline, or diesel driven compressors. They may also be ordered as retrofit kits to be installed on existing compressor systems.

Cartridge Monitor

The Mako cartridge monitor has its sensor located inside the chamber, not the disposable cartridge. There is no need for the added expense of purchasing a cartridge with an installed sensor.
