We have analyzed an alternative method of instruments calibration, which involves the transfer of a magnitude unit from standards that implement the contact measurement principle.

The study also has showed that the proposed alternative calibration procedure allows:

(a) to reduce the number of calibration instrument points without loss of calibration quality and save up to 40% of the calibrator’s time;

(b) to reduce capital investments by changing the set of equipment for calibration; (c) to reduce annual operating costs by 12%;

(d) to receive an annual economic effect up to 185 thousand rubles (without taking into account the savings of the calibrator’s working hours).

Thus, we have shown that the use of a liquid thermostat with a special insert as a source of radiation reduces the cost of calibration.

In addition, using the proposed methodology, the laboratory for calibrating pyrometers overcomes the profitability threshold when calibrating twice as few devices.
