General information

Catalogue of developments

Catalogue of developments/COMPLEX OF TECHNOLOGIES FOR TEMPERATURE CONTROL/1.Periodical temperature control
1.2 Contactless temperature control

Thermometers portable optical contactless

Thermometer portable contactless one-colour

Thermometer portable contactless two-colour


  Contactless temperature control of solid, liquid and gaseous media in metallurgical, chemical-recovery and refractory productions.

Operation principle

  It is based on brightness or brightness ratio dependences on temperature of the controlled object.

Main tеchnical characteristics

Range of measuring temperatures, °С 200...2500.
Measurement error, % ≤1,0.
Mass, kg <1,0.


  Due to the spectral ratio method, two-colour thermometers have higher metrological characteristics and, consequently, wider application field, as well as more convenient in practical use.

Теchnical-economic efficiency

  Thermometers allow you to stably obtain metal products with determined properties at the lowest possible expenses.
