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
ue-gas stream of fossil-fuel red furnaces and boilers.
Ordering Information:
Part No. Description
19-8104 Monoxor III, includes 4 ‘AA’ batteries, probe & hose assembly
with integral water-trap / lter, and a hard carrying case
19-8105 Monoxor III, includes 4 ‘AA’ batteries, probe & hose assembly
with integral water-trap / lter, hard carrying case, plus
an IrDA printer with an assortment of printer accessories
including an AC adapter, roll of paper, in-car charger, belt
clip, and magnet
The analyzer detects and displays the presence of CO by rst drawing in a
gas sample from the area being tested by the analyzer’s built-in motorized
pump. The gas sample is next directed into a sensor chamber where the
sample is analyzed for the presence of CO. If CO is detected, the CO ppm
level is displayed on the analyzer’s LCD.
A permanent record of the detected CO level, along with the current time
and date, can be made by using the optional wireless IrDA printer.
A backlight enables the operator to read the display in dimly-lit areas. A
power-saver feature causes the backlight to automatically turn OFF after
10 minutes, and causes the analyzer to shut OFF after 20 minutes of inac-
tivity. The power saver feature, however, is disabled while the detected CO
level is above 50 ppm.
When the analyzer is used to measure the CO content in ue-gas, a rigid
stainless steel probe with handle is provided that allows gas samples to
be taken from within the ue stack. An integral water-trap / lter pre-
vents water and soot from being drawn into the analyzer. The probe can
also be used in ambient testing to draw in gas samples from cramped and
conned areas.
If the analyzer is turned OFF while a high level of CO is still present
within the unit, the analyzer’s pump remains running and the unit will
not turn OFF until the detected CO level drops below 50 ppm.
