Not bad, but I'd still like to see a modular one for a reasonable price that could add helium. Screw on each module, and a triple display would show He, O2 and Co. That would be worth something.
O2 + CO analyzer choices.

define reasonable price
It is a rechargeable battery.

I think it should be possible to add Helium for only a few hundred dollars. If the whole thing with 3 modules and 3-line display could be done for less than $800, you would have the entire market to yourself. But the key is to make it modular, so people could buy the O2 and CO analyzer and then add the He module later after they start diving trimix. The cost difference between the 2-line display you show and a 3-line should be minimal. I'm just looking toward the future, as you have always shown yourself to do.
Yes.
cootwo uses a standard rechargeable AAA Li-Ion battery (LIR10440). ~$3 online
It depends on what brand/model you get.
The model we plan to use has a ~300 cycles life.
Each cycle is good for several hours (we think ~10) of continuous use (if you disable the display and use only the smartphone it should be ~100 hours)
How many analyses do you do in 1 hour? And in 10? And in 3000?
A properly done analysis should be ~2 minutes (you want the sensors to stabilize ... they are chemical devices)
So, if we got this right ....
- 30 analyses x hour
- 300 analyses x cycle
- 90,000 analyses x battery ...
1 battery should be enough for quite some time. But, if you want you can replace it
