[PSUBS-MAILIST] O2 gauge

Wed Nov 26 08:59:29 EST 2014

i have no idea why the pics are turning sideways, they are straight until i
press "send".

3rd i have the Orion plus.  I didn't buy this, a relative who is a miner
gave it to me.  Must have got lost in the Colliery changing room...

Anyway, it does 4 gasses, Oxygen, Carbon Monoxide, Methane and
Hydrogen.  Seems very good.  If bought new, you can get one that does co2
instead of co.  Not sure the other gases are of any concern.  Maybe
hydrogen i suppose from the batteries.  The problem with this one is that
it has a sampling fan inside, so its constantly sucking in air through that
pipe at the top.  Its not a major drama but it makes it a bit noisy.
This would be the best one if it did co2 instead, but i wouldn't buy one,
too expensive.  The orange thing is my CO2 monitor.

Kind Regards
James
