PTSV platinum vibration-resistant reference resistance thermometers

PTSV platinum vibration-resistant reference resistance thermometers
PTSV platinum vibration-resistant reference resistance thermometers

Designed for

PTSV platinum vibration-proof reference resistance thermometers (hereafter thermometers) are designed for verification of temperature measuring instruments in accordance with State verification schedule for temperature measuring instruments (GOST 8.558-2009) and for use as a temperature measuring instrument of improved accuracy in various industries and scientific research.

Thermometers are portable devices, composed of primary thermal transducer - a sensitive element of a platinum thermometer (CHEPT) and a protective housing.

The principle of operation of thermometers is to use the temperature dependence of platinum electrical resistance.
