275988 - Miller SAR BreatheAir CO Monitor Calibration Kit with Regulator and Case

Protect Your Lungs with Accurate Air Monitoring

As a professional welder using a Supplied Air Respirator (SAR), you rely on your equipment to deliver clean, safe breathing air, especially when working in confined spaces or with hazardous fumes. The Miller SAR BreatheAir system is your lifeline, filtering out contaminants before they reach your helmet. However, the Carbon Monoxide (CO) monitor that stands guard on your filtration panel needs regular checking to ensure it's telling you the truth. The Miller 275988 Calibration Kit is your tool for peace of mind, giving you the power to verify that your safety alarms will trigger exactly when they should.

Carbon Monoxide is a colorless, odorless, and tasteless gas that can be fatal if it enters your air supply. Your Miller BreatheAir system has a monitor designed to catch this, but sensors can drift over time. This calibration kit allows you (or your safety officer) to "teach" the monitor what clean air looks like and what dangerous air looks like. The kit comes with a cylinder of "Zero Air" to set the clean baseline, and a cylinder of "10ppm CO" to simulate a danger scenario. By running these gases through your machine using the included regulator and hose, you confirm that the sensor is reading correctly and that the alarm will sound if CO levels ever spike in your airline.

The kit is designed for ease of use in the shop or on the job site. The quick-disconnect hose snaps right into your Miller panel, making the process fast and frustration-free. The included hard case keeps everything organized, so you aren't hunting for the regulator when it's time for a monthly check. Don't leave your safety to chance or assume the green light on your panel is accurate without proof. With the Miller 275988 Calibration Kit, you take control of your respiratory safety, ensuring that every breath you take under the hood is as safe as it should be.
