    Monoxor III 1.0 INTRODUCTION The Monoxor III is a portable analyzer designed to detect and display concentrations of Carbon Monoxide (CO) gas between 0 and 2000 ppm. The analyzer is capable of testing for CO in both ambient room air, and in the flue-gas stream of fossil-fuel fired furnaces and boilers.

    Monoxor III 4.8 Operating Tips • When an analyzer is brought in from a cold vehicle, let it warm up slowly to minimize condensation. Temperatures below freezing will not damage the analyzer; however, bringing a cold analyzer into a warm, humid environment may cause condensate to form inside the case.
