275991 - Miller Calibration Gas - Carbon Monoxide 20 PPM - 17L Cylinder

Precision Calibration for Welding Safety

The Miller 275991 Calibration Gas is a critical maintenance component for industrial welding environments utilizing advanced fume extraction and monitoring systems. This cylinder contains a precise mixture of Carbon Monoxide (CO) at a concentration of 20 Parts Per Million (PPM). It is specifically engineered to calibrate and verify the accuracy of CO sensors found in Miller Filtair systems and other compatible air quality monitoring devices. Regular calibration is not merely a recommendation but a necessity to ensure that safety equipment functions correctly, detecting hazardous gas levels before they pose a risk to operators.

Ensuring Sensor Accuracy and Reliability

Gas sensors, particularly electrochemical CO sensors, are prone to drift over time due to environmental factors, age, and exposure to contaminants. Without regular calibration using a known standard like the Miller 275991, a sensor may provide false readings—either failing to alarm during a dangerous leak or causing nuisance alarms that disrupt production. By introducing this 20 PPM span gas to the sensor, maintenance personnel can adjust the device's response to match the known concentration, restoring confidence in the equipment's ability to protect worker health.

Compact and Efficient Design

Supplied in a 17-liter cylinder, this calibration gas offers a balance between portability and capacity. The compact size makes it easy to transport to various stations within a facility or to remote job sites where portable fume extractors are in use. Despite its small footprint, the 17-liter volume provides sufficient gas for multiple calibration cycles, making it a cost-effective solution for routine maintenance schedules. The cylinder is designed to work seamlessly with standard calibration regulators (sold separately) to deliver the correct flow rate required for accurate sensor testing.

Compliance and Safety Standards

Maintaining a safe welding environment involves strict adherence to OSHA regulations and industrial hygiene standards regarding exposure to toxic gases like Carbon Monoxide. Using the Miller 275991 Calibration Gas helps facilities document their compliance by proving that their detection equipment is tested and verified regularly. This proactive approach to safety management minimizes liability and, most importantly, safeguards the well-being of welders and support staff working in areas where combustion fumes are present.
