I recently purchased a testo 327, and now do not need my tech 60. I purchased the tech 60 a few years ago and knew at that time it needed an o2 sensor. Well I never got around to getting one so it would need an o2 sensor and probably be good to be calibrated. I got it from someone who only used it twice on their own home heating unit. It is in excellent condition, like new, not even any heat marks on the probe. Comes with the analyzer, flue probe, case, instructions. I know the case is a bacharach case I just don't know if its the right case for the unit. Anyway if anyone is intested in it feel free to email me.
I paid 200 for it, I'd like to get close to that but would consider offers.
Thanks, Jason
