Temperature Calibration

In this laboratory, based on the scope of certification and national and international standards, calibration of liquid thermometer in glass, calibration of bimetallic and filled hand thermometer, resistance thermometer calibration, thermocouple calibration, temperature environment calibration, temperature calibration, temperature display calibration, thermometer calibration Non-contact (radiant) thermometer calibration, hygrometer calibration, electric furnace calibration, incubator calibrator and humidification environment calibration are calibrated by experienced and trained personnel.

Temperature environments including bath calibration and furnace calibration used in calibration laboratories, for calibration of various types of temperature sensors, calibration of thermocouples, calibration of platinum resistance thermometers, calibration of thermistors, calibration of temperature switches and sensors with temperature sensor and sensor They can be categorized as follows:

Temperature and humidity calibration includes:

  • Freezing point bath
  • Freezing points
  • Triple point of water
  • Fluid baths (water, oil, powder, salt, etc.)
  • Refrigerator or freezer
  • steam bath
  • Dry bath or stove equipped with metal blocks
  • Tube furnace
  • Data loggers
  • Probe thermometers
  • IR thermometers
  • Thermocouples
  • Dry heat ovens
  • Food safety probe thermometers
  • HACCP certified thermometers
  • Water baths

All temperature measurement calibrations are performed as per the following Australian standards and HACCP standards:

  • AS 1006-1995
  • AS 2853-1986
  • AS 2487-2002
  • AS 2190-1995
  • AS 2819-1985
  • AS 2931-1985
  • AS/NZS ISO 10012:2004
  • ASTM E230-93 012:2004

Three important parameters (characteristics) in temperature environments are:

Stability: A measure of temperature stability over time (short-term or long-term)

Uniformity: A measure of temperature inequality in different physical locations of the temperature environment

Depth of Immersion: A measure of the ability to calibrate sensors of different lengths (long and short)

Requirements for baths or calibration furnaces as comparators are:

  • The temperature of the ambient temperature (bath or furnace) should be controlled so that the measuring connection of the thermocouple is calibrated at the same temperature as the reference thermometer.
  • In an area of ​​the temperature environment where calibration is performed, there should be conditions of temperature and spatial uniformity in terms of temperature
  • The uniformity and temperature stability of the above calibration zone should be measured and monitored through appropriate and regular methods such as drawing control charts and, if necessary, during the test, and if necessary, necessary corrections should be made.
  • All temperature sensors or other temperature devices under the reference calibrator and thermometer should be immersed in the appropriate amount in this area to ensure that the temperature of the reference connection point is not greatly affected by the effect of thermal conductivity during the physical structure of sensors and reference temperature thermometers. Take
  • To prevent contamination of sensor wires, especially for thermocouples and to insulate them from each other, direct contact of fluids and liquids in baths should be avoided.
