COMPACT ZERO-THERMOSTAT Russian patent published in 2007 - IPC G01K7/00 

FIELD: the invention refers to measuring technique particularly to thermostatic arrangements for control of soldered joints of thermocouples.

SUBSTANCE: a zero-thermostat has an exterior cylindrical chamber fulfilled out of material with thermal conductivity. A thermal electrical module is joined to the upper foundation from the inner side with a hot soldered joint. The cold soldered joint of the thermal electrical module is in a good thermal contact with the cylindrical chamber fulfilled out of material with high thermal conductivity. Inside the chamber there is distilled water divided with the frontier of division on solid and liquid phases.

EFFECT: increases accuracy of thermostatic control of soldered joints of differential thermocouples and reliability in interpretation of conducted measurement.
