I'd sell it for $25 shipped... I only put another 2 months of use on it, and I put a new 9v battery in it (not much cost there I know). Yeah you would need a probe, and calibration fluid.

Hi. Thanks for the offer! How much are you looking to get for the unit? Im guessing I would just need to pick up a new probe? Thanks again!
