In reply to # 1510641 by Tonyfixit The sensor cable is only about 18" long, I guess I could order a longer K type sensor for another $1.According to the ad, that unit uses a thermistor rather than a thermocouple. You should be able to attach longer wires if you want.
I think I see a voltage regulator on the board, so noise on the power shouldn't be a problem. If noise on the pickup line becomes a problem, you could try using shielded cable instead of a plain pair; but I think it's unlikely. Easier to just turn the hysteresis up a bit.
