Most Popular Methods for Temperature Calibration

When it comes to temperature calibration, several methods are commonly used to ensure accurate and reliable measurements. Let’s explore some of these key methods:

• Comparison Calibration: Involves comparing the device under test (DUT) with a reference thermometer in a stable environment, such as a calibration bath or dry block calibrator.
• Fixed Point Calibration: Utilizes the known physical properties of substances at specific temperatures (e.g., the melting point of ice or the boiling point of water).
• Simulator-Based Calibration: Calibrates only the electronics (voltage or resistance) of the temperature measurement/control system using a temperature simulator.
• Dry-Well Calibration: Combines both electronics and sensor calibration by placing the thermometer, meter, and probe in a dry-well set to the desired test temperature
• Dry-Well Calibration with Reference Thermometer: Uses a stable heat source (dry-well) and compares the thermometer against a more accurate reference thermometer placed in an adjacent hole in the well.
