Monoxor Plus Manual Section 1. Overview Overview 1.1. Introduction Thank you for investing in a Bacharach Monoxor Plus carbon monoxide (CO) analyzer. To assure proper use and operator safety, please read the contents of this manual for important information on the operation and maintenance of the analyzer. 1.2. Conventions WARNING: A warning statement denotes a potential hazard associated with the use of this equipment.
Monoxor Plus Manual Overview 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.
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.
Overview Monoxor Plus Manual 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 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 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: • • • • • spare filters Fyrite User Software (FUS) USB cable (type A to mini B) Infrared Data Association (IrDA) printer with four disposable “AA” alkaline batteries printer paper.
