Used Analytical Industries 4001 Helium Oxygen Trimix Analyzer. In good working condition, with some wear on the outside (see photos). Battery replaced in August 2022. O2 sensor replaced in April 2022. Helium sensor was manufactured in September 2016. I spoke to AII: because the helium sensor operates by thermo-conductivity it does not degrade in a predictable way like the O2 sensors. A-I-I indicates a 10 year helium sensor life, depending on usage and treatment (new sensor was quoted by A-I-I at $309).

you say "see photos" but there are no photos...

O2 sensor date == April 2022
Helium sensor date == September 2016 (I purchased it November 2016 as original owner -- receipt available)

I spoke to AII: because the helium sensor operates by thermo-conductivity it does not degrade in a predictable way like the O2 sensors. A-I-I indicates a 10 year helium sensor life, depending on usage and treatment (new sensor was quoted by A-I-I at $309). I used the sensor only for my own trimix tanks -- it was never used in a commercial application and no one else used/abused it -- it otherwise was stored in a temperature controlled garage. That said, I can't promise a full life.

Given the partly used Helium sensor I took another $50 off the price, now $600.
