A hand-held instrument designed to locate CO in ambient air as well as stack gases.

Monoxor II

Bacharach's Monoxor® II is a continuous sampling instrument that quickly and accurately measures levels of CO between 0 and 2,000 ppm. The Monoxor® II has a stainless steel probe with four feet of tubing to sample CO found in flue gases of residential furnaces, combustion appliances, commercial and industrial boilers.

With the addition of the Breath Analysis Module (BAM) to the Monoxor® II, it becomes a powerful tool in determining the presence and level of CO in the bloodstream. The Monoxor® II is also available in a high range version (0-85,000 ppm) for vehicle emissions testing and forklift tuning.
