Reliable and consistent

Our facilities have 40 of these monitors. This unit is easy to read, easy to operate, easy to calibrate and always reliable. We had three other lower cost brands in the mix. They were name brands, but did not hold up to the standards this one does. I replaced every other one with this brand. This is the only monitor we will buy from now on. It holds calibration and rarely needs to be adjusted. We have some units which were installed 14 years ago and the sensors are still working like new.

Simple and effective

Easy to install, and works great for monitoring oxygen levels nearby. Tested using calibrant gases and measured O2 values matched very closely.

Peace of mind.

I'm a hobby welder with tanks in my walk-out basement shop.
The 221R monitor provides peace of mind that a leaky valve will not suffocate anyone in my family. Pricey? but actually very affordable insurance.
