Hi Amber,
I don't know what your budget is like, but we use multiple of these units and they hold up really well over many years. We've had some in place for 15 years now and they're still working beautifully. They auto-calibrate and just need the little inlet filters changed now and then.

We like to place the sensor so that the inlet is at more or less breathing height for a short person, like 4-5 feet off the ground.

Hello,
We use liquid argon for our ICP-MS indoors and I'm looking to increase our safety by including an oxygen monitor in the room. It would be used to ensure if the argon tank releases pressure/vents, the room is safe to occupy.
We have two doors to other rooms to control access to the space and/or allow fresh air in, fans and a fume hood in the room with the gas tank for air exchange as well as building air exchange in the ceiling.
We will also be venting the release valve into the fume hood to avoid pressure release argon from filling up the space.
Any information or guidelines for increasing our safe usage of this would be appreciated.
Thank you~!
