$190.00 Oxycheq Expedition O2 analyzer

[divad]

I just got one from Golem Gear. I've tested everything around my dad's house, except for my dad's cat's farts, and really like it. I thought the calibration knob was way too sensitive so I put an old o-ring (slightly smaller than the knob) over it, which fit perfectly in the indentation between the knob and case, (very) effectively dampening it.

Thanks Oxycheq and Golem Gear.
