Temperature Equipment Calibration

Temperature equipment calibration is the process of comparing the readings of a temperature measuring device (such as a thermometer, sensor, or thermal imaging system) against a traceable reference standard to ensure accuracy and reliability.

It ensures that instruments used in industrial, laboratory, or commercial settings provide precise temperature measurements, which are critical for quality control, safety, and compliance with international standards.

🌡️ Common Temperature Instruments Calibrated

  • Digital and analog thermometers
  • Resistance Temperature Detectors (RTDs)
  • Thermocouples (Type J, K, T, etc.)
  • Infrared thermometers and thermal cameras
  • Temperature transmitters
  • Temperature controllers and indicators
  • Data loggers

🧪 Calibration Methods

Calibration is typically performed using traceable equipment and methods such as:

Dry Block Calibrators – Provide a stable temperature source for probe insertion.

Liquid Baths – Used for calibrating multiple sensors with uniform thermal distribution.

Temperature Chambers – Allow calibration under environmental simulations.

Comparison with Reference Thermometers – High-accuracy standards traceable to national/international labs.

    📝 Key Steps in Calibration Process

    Initial verification of the instrument’s reading at defined set points (e.g., 0°C, 100°C).

    Comparison against a traceable standard.

      The most common and most frequently measurable variable in the industry is temperature. It greatly influences many physical features of matter, and its influence on quality, energy consumption, and environmental emission is significant.

      While standards determine the accuracy to which manufacturers must comply, they nevertheless do not determine the permanency of accuracy.

      Therefore, the user must be sure to verify the permanency of accuracy. If temperature is a significant measurable variable from the point of view of the process, it is necessary to calibrate the instrument and the temperature sensor.

      We offer the following temperature calibration services:

      • Thermometers
      • Infrared (IR) thermometers
      • Temperature sensors
      • Thermocouples
      • Digital thermometer with TC and RTD sensors

      📌 Conclusion

      Temperature calibration is essential to maintain accuracy in measurement-critical operations. Partnering with a competent and accredited provider like DAS Certification ensures compliance, quality, and confidence in your measurement systems.
