Overview Monoxor
Plus Manual
CAUTION: This analyzer is not intended to be used on a continuous basis.
CAUTION: Do not store instrument or its sensors with solvents or products that contain solvents.
CAUTION: Except for sensor and battery replacement, this analyzer should only be opened and/or serviced by authorized
Bacharach personnel. Failure to comply may void the warranty.
HAZARDOUS AREA WARNING: This instrument has not been 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.
CAUTION: 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
• maintenance personnel
• safety 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).

netzerotools.com
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.

A programmable inactivity timeout causes the analyzer to initiate shutdown mode if no key presses occur for the specified time period. If the analyzer initiates automatic shutdown or is turned OFF manually while a high level of CO is still present within the unit, the automatic CO purge feature forces the analyzer’s pump to remain on until the detected CO level drops below 50 ppm.
The instrument is supplied with the following components:
• probe and hose assembly
• four disposable “AA” alkaline batteries
• hard carrying case
• factory-calibrated and installed CO sensor.
Depending on the model and kit, some or all of the following components are included:

4.6. Taking Differential Temperature Measurements
In certain combustion applications, it may be desirable to have a differential temperature measurement. Use the Diff Temp menu and either the optional probe assembly with thermocouple (P/N 0019-7111), or one of the optional K-
Type thermocouples (P/N 0104-1798 or P/N 0104-1797) to accomplish this task.
The Monoxor Plus calculates the differential temperature based on two sampled temperatures (T1 and T2) which it reads from the optional probe assembly’s thermocouple (which is connected to the T-STACK connector of the instrument). 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. Use the following procedure to perform a differential temperature measurement.

5.1. Serviceability
The instrument operator is able to easily replace the following components without the use of tools:
• probe assembly
• probe filters
• batteries
• B-Smart CO sensor
• printer paper.
Additionally, a technician, with the use of factory-provided instructions, can:
