 Rick,You can also buy a O2 meter that just tells you when the O2 is low or high but does not give percentage.  They are pretty cheap.  Hank

 Thanks guys,since I didn't hear anything back at all from my post, I figured it didn't go out properly. I plan on keeping it as simple as possible regarding lap tops and things hooked up to it as that stuff is way out of my league! Rick

Rick,I did receive the original post, but like Jon & Cliff I am going touse a computer to receive the signal from my sensors.   It sounds fancy, but instead of having several sensors for O2,CO2, pressure, humidity, temperature, water temperature etcwith their individual electronics & display units, you can pick thesensors up reasonably cheaply & use the one computer& display screen for all.Alan

Rick,there is the Famous Elcheapo O2 analysing kit, that you assemble.The cost is not a lot more than the included sensor. I am not sure of the voltage, but would guess you would use a 9Vbattery. https://www.oxycheq.com/el- cheapo-ii-analyzer-kit.htmlAlan

Thanks JonYeah I hope he was mistaken as well though he was in tech support at OTS. If that’s the case, I’ll lose coms less than a third of the way down to my design depth!Hank, didn’t you post once about an affordable O2 monitor that you were using?Rick

I saw it Rick, just haven't completely decided yet so didn't respond, however you did get me thinking about it again and I believe I'm going to use an O2 sensor intended for rebreathers that will be interfaced with an Arduino microprocessor.  They are manufactured by Analytical Industries and distributed by Dive Gear Express, most under $100 and have a life of two years.
I have no experience with OTS yet but sure hope it is better for more than 100 feet.

I sent out a post the other day regarding what others were using for a 12 volt oxygen sensor but didn't get a response so not sure it went threw?? Maybe I typed in the wrong address? I was on the phone with tech support at OTS the other day and asked him what range I could expect under standard conditions and he said about 100'. Can anyone out there speak to that? Rick______________________________ _________________
