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.
