  • Page 6: General Safety Statements

    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.
  • Page 7 Monoxor XR User Manual ® Ambient CO CO gas is colorless, odorless, and deadly. Test CO levels in suspect Pambient air. Perform an automated 15-minute test, watch live values, or view a dynamic CO graph over time. Fig. 1-1: Perform an Ambient CO test and watch live values, or view a dynamic CO graph over time 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.
  • Page 8 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 Bacharach at 1-800-736-4666 ® or email help@mybacharach.com.
