Temperature Calibrator
A *Temperature Calibrator* is a device used to simulate or measure temperature to calibrate temperature sensors, thermometers, thermocouples, RTDs, and other temperature measurement instruments. It ensures these instruments provide accurate and reliable temperature readings.
Types of Temperature Calibrators:
*Dry-block calibrators:* Use a heated metal block with holes to insert sensors.
*Liquid bath calibrators:* Use a temperature-controlled liquid for immersion of sensors.
*Portable handheld calibrators:* Battery-operated, used for on-site calibration.
*Fixed or benchtop calibrators:* Larger and more precise, used in labs.
How a Temperature Calibrator Works:
1. It generates a stable, known temperature.
2. The device under test (DUT) is exposed to this temperature.
3. The DUT’s reading is compared against the calibrator’s known value.
4. Any deviation is noted and the instrument can be adjusted or recalibrated.
Common Features:
Temperature range (e.g., -50°C to 700°C)
High stability and accuracy (±0.1°C or better)
Digital display and controls
Compatibility with different sensor type
