To calibrate the Klein Tools ET110 Carbon Monoxide Meter, it is recommended to have it done by a professional in an environment with a known concentration of carbon monoxide. Calibration in an area containing carbon monoxide will result in incorrect calibration and lower than actual readings. For more information on calibration and sensor replacement, please contact Klein Tools customer service.
Note: The manual does not provide specific instructions for user calibration of the meter.
