information could result in serious personal injury or death.
CAUTION: A caution statement indicates a potentially hazardous
situation which, if not avoided, may result in minor or moderate

CAUTION: Do not store instrument or its sensors with solvents or
products that contain solvents.
CAUTION: Except for sensor and battery replacement
Bacharach personnel. Failure to comply may void the warranty.
HAZARDOUS AREA WARNING:
designed to be intrinsically safe for use in areas classified as
hazardous locations. For your safety,
DO NOT use it in hazardous
(classified) locations.
CAUTION: Do not use flammable or combustible substances (like
carburetor fluid used for cleaning the probe) near an open flame.
When the instrument is used in an inefficient oil-fueled
appliance where there is a high emission of soot, the probe’s
sample filter may become clogged. Before every use check the
filter to confirm it is clean or replace it with a new filter.
To prevent soot intake and a clogged filter, a smoke test should be
performed before operating under such conditions. This ensures
that the furnace or boiler is burning at a level appropriate for the
use of this instrument.
1.4. Product Overview
The Monoxor Plus is a portable hand-held carbon monoxide analyzer for use
in residential and light commercial applications. It is intended to be used by:
• HVAC contractors
• home inspectors
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.
A backlight enables the operator to read the display in dimly-lit areas. The
displays and menus are available in multiple languages (English, French and
Spanish).

Monoxor Plus Manual Overview
The analyzer detects and displays the presence of CO by first 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 given on
the analyzer’s main display. A trending screen (accessible from the RUN
screen by using the right or left arrow key) shows dynamic CO levels graphed
over a programmable time period (from 30 seconds to 15 minutes). In addition
to the visual notifications, you can set a CO alarm limit, above which an audible
alarm buzzer will beep repeatedly. An audible alarm with a slower beep
frequency occurs when the batteries are low.
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. Test records can
also be saved in memory.
The Monoxor® Plus can calculate a differential temperature based on two
sampled temperatures (T1 and T2). After you take the two sample readings,
the differential value (T1-T2) is calculated, optionally saved in memory,
displayed on the main run screen, and is shown on printouts.
An ambient CO feature takes approximately 15 minutes to complete and
provides a minute-by-minute snapshot of CO readings, as well as a “Max CO”
value that represents the highest CO reading measured during the entire test.
Results can be saved to memory and/or printed. Use the optional CO
Appliance Kit (P/N 0024-8555) to perform an ambient CO measurement.
A calibration reminder can be set to occur every 6, 8, 10, 12, or 15 months after
the last calibration. (Select “Never” to disable this feature.) Regular calibration
periods of 6 months to 1 year are recommended. The calibration reminder
value sets a time period after which the analyzer displays a calibration
reminder message during warm-up.
To avoid the need for manual CO sensor calibrations, the B-Smart® Sensor
program is supported with the Monoxor
Plus. After enrolling in the program,
pre-calibrated replacement B-Smart® CO sensors are shipped at predetermined intervals of your choice.
• Choose a program start date that best suites your needs.
• Receive a pre-calibrated B-Smart® sensor.
• Return your old sensor in a returnable, pre-labeled container.
Benefits include no downtime, self calibration, convenience, and cost savings.
For additional information about the B-Smart® Calibration Program, contact
