The microprocessor controller in CAMAC standard for temperature regulation and stabilization of an external object (electric furnance, thermostat) is described. The controller has two control regimes - parallel and serial regimes and has been controlled by personal computer PC/XT/AT. The apparatus that has been created and software supply allow linearly to raise or to lower temperature of samples to indicated value with different rates, to stabilize temperature on a level is set, to record a graph of current temperature both at time of heating or cooling down and at time of stabilization with different frequency that is set by the program. 3 refs.; 3 figs.
