Clemco's 10 PPM test gas is specifically for use with the Clemco CMS-3 and CMS-4 Carbon Monoxide Monitor.
This bottle of test gas contains approximately 34 mins of calibration time.
Using the proper test gas is important for successful calibration testing of your CO monitor. A monitor out of calibration may fail to alert the operator to toxic gases.
Note: thoroughly review and understand calibration testing of your CO monitor before testing or calibrating your instrument. Information on calibration testing with test gas can be found in the operation manual of your CMS-3 and CMS-4 Carbon Monoxide Monitor.
