STANDARD TEMPERATURE METER

The standard was established and is in operation since 2004

Composition:

  • measurement unit;
  • temperature sensor

 Metrological characteristics:

  • ambient temperature measurement range – from 193 K to 693 K (from –80 °C to +420 °C);
  • confidence limits of absolute temperature measurement error at confidence level 0,95 and coverage ratio k=2:

± 0,010 К (from 193,15 K to 273,16 K);

± 0,010 °C (from 0 to 231,928 °C);

± 0,030 °C (from 231,928 to 419,527 °C);

  • the limits of accepted absolute resistance measurement error (0; 10; 100 Ohm) — not more than ± 0,0015 Ohm;
  • measurement instability — not more than 0, 003 °C (0,001 Ohm) for 3 months

Sources of traceability:

The Republic of Belarus, BelGIM, National standard of temperature unit – Kelvin

 Scope of application:

Is applied as a standard instrument and for precision measurements of temperature in:

  • industry;
  • power-engineering;
  • public health;
  • construction;
  • regional metrological centers of Gosstandart
