Digi-Q Pit Probe Fail

I had issues with my probe once. I spoke to the guys at Guru, and they told me the probes were rated for 350-400, but it was not recommended to go over 300. They also made mention to make sure they do not get bent or pinched. They sent me new probes, and they have been flawless. However, i never go above 300, and try to keep em closer to 250.

I was the guy that fixed laboratory equipment for my lab back in the '90s and a lot of the equipment had thermocouples.  Any moisture (especially with something like salt) makes them short out.  Drying them would sometimes fix them.  The insulation is often braided fiberglass, which is porous.

Good Luck!!

In all the years of talking with the Guru folks when testing their units, they have never told me that the probes have to be kept below 400.  The original teflon coated cables were rated to 450.  I've used one set of probes over 100 times at 400 degrees and it took about 7 years before it failed.  The DigiQ unit itself can control (and allows you to select) temperatures up to 475, so I think their probes are a bit hardier than what this person told you.
