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
conned 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.

3.0 PREPARING THE ANALYZER
FOR OPERATION
To prepare a new analyzer for operation, you must install four ‘AA’
Alkaline batteries, install the probe (if needed), and set the correct time
and date as described in the following paragraphs.
For your convenience, and to ensure that the analyzer will provide reliable
CO readings, the CO sensor was installed and the analyzer calibrated on
500 ppm CO at the factory.
3.1 Battery Installation
Install fresh batteries as described below. Check the analyzer for sufcient
charge prior to each use. Replace the batteries if the low-battery symbol
appears in the lower right corner of the LCD. To install batteries:
1. Remove battery cover from back of unit (see Figure 3-1).
2. If old batteries are installed, remove and properly dispose of the
batteries.
3. Observing the polarity markings inside the battery compartment,
install four ‘AA’ Alkaline batteries.
4. Replace battery cover.

3.2 Probe Installation
Install the probe if the analyzer is going to be used for ue-gas CO mea-
surements, or if gas measurements need to be taken from a cramped or
conned area.
To install the probe, simply slide its hose over the GAS inlet of the ana-
lyzer (see Figure 3-2).
