Hi all,

I need to replace the oxygen sensor in my lab. The one I have is GFG ZD21
(https://www.gfgsafety.com/us-en/products/fixed-gas-detection-systems-transmitter/zd21)
and I have found that the sensors don't last very long and replacement ones are
very difficult to calibrate. Right now it is hard-wired in the wall with a
sensor at the ceiling and the floor. I don't really care too much about having
two sensors/channels with a replacement unit, but I have existing conduit to
run two sensors.

Would be interested in hearing what oxygen monitors you use in your labs/facilities.
I'd also be interested in a remote monitoring option if it isn't a zillion dollars.
