Closed TekCheck and Nuvair Analyzers That I Don't Know Much About

[cklaus]

I purchased some gear and included were two analyzers I don't know much about. I already have an analyzer I use and like so I'm not trying hard to educate myself on a couple of older units. Instead of storing them or trashing them, I thought I'd list them for anyone who may find one or both useful. I have no idea if these work, are missing pieces, or anything more than the pictures show and I think the price reflects that. They don't power up, but the lack of a battery/power source may be the only reason. Once they have power, they may work without further problems.

If you have experience with these and like to tinker, let me know.

WARNING: When analyzing gas, it is essential to have accurate information. Failure to do so may kill you. Please only use these if you are completely confident that they work and are accurate.

Asking: Make me an offer + Shipping
I'm happy to sell one or both.

I think the primary reason a used sensor is hard to sell - is because once the sensor goes out you end up replacing the entire thing. Buying a used sensor is just a gamble.
