An electronic circuit has been developed which acts as an electronic ice bath for chromel-constantan thermocouples. The electronic ice bath is accurate to within plus or minus 0.2C from -25C to +50C. Simultaneously, the thermocouple output is scaled and linearized such that the temperature can be read directly in C with a sensitivity of 100 mV/C with 0 VDC at 0C. Circuit diagrams and construction considerations are included to allow the reader to construct a functioning unit.
