hi, there,

well I was just wondering if you guys know the small LCD temp readout that can read negative temps, and would be able to take probes like type K

something like the one the promis used or the vapo that would be able to show letters and at least two temps,


thanks

Look for one of these controllers:

- Eliwell EWPC-901
- Dixell XR30C
- Carel IR32 series.

Be sure to use a PTC, thermocouple or Pt100 sensor. NTC's are no good for low temps.

Also, standard household thermometers are no good either. This picture says enough I hope:
