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: 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.
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 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.
