Up for sale are TWO Heathkit ID-1390 Digital Thermometers. Both function, in a way. The displays work and everything appears fully functional, but calibrations are way off and it has been a constant struggle to achieve and maintain calibration (the procedure is in the manual). One unit has been modified to use an LED display - the mod is documented and one manual is included. Three temperature sensors are included although one has no housing and the other is just two diodes in series that I wired up. Use these for parts, or with some care you can probably get at least one calibrated.
