A thermoregulator for a helium cryostat and helium-level indicator are described that are based on an MK-64 programmable picket calculator with a built-in analog-digital converter. The temperature and helium-level sensors are TVO carbon resistors. The MK-64 makes it possible to maintain or change by program a temperature in the range of 1.2-77/sup 0/K with an accuracy of 0.05-0.5/sup 0/K and also to output to the calculator display and peripheral devices the temperature and any function of temperature. The calculator display indicates the presence of helium in the cryostat and the level of the helium tank.
