The Bacharach Monoxor Plus Carbon Monoxide Analyzer is an advanced, affordable, portable carbon monoxide analyzer that delivers quick, accurate CO (0 to 2,000 ppm) and temperature measurements for residential and commercial contractors, safety technicians and weatherization specialists to efficiently perform indoor air quality and safety checks. In addition to ambient air CO readings, its probe and hose assembly (with water trap/filter) enables direct CO sampling of flue gases, residential furnaces, gas appliances or commercial boilers. Analysis is instant and intuitive with push-button operation, selectable display options and easy set-up. Its inactivity shut-off feature is disabled when CO readings exceed 50 ppm.

The Monoxor Plus provides reliable, long-running performance in a handheld unit and utilizes exclusive B-Smart® pre-calibrated CO sensor technology to enable in-field sensor replacement and minimize instrument downtime and maintenance costs. An optional reporting kit with wireless IrDA magnetic printer for documenting time/date coded results is available as well as PC software for custom configuration.
