Introduction
A dry block calibrator is more than just equipment—it’s essential for quality control in industries where even a 0.5°C error can mean costly failures or safety risks. Tempsens dry block temperature calibrators provide quick, precise, and traceable calibration. As a leading manufacturer, Tempsens offers solutions built for peak performance and minimal hassle.
A Dry block temperature calibrator is a precision temperature calibration device for validating and calibrating temperature sensors such as thermocouples, RTD, and thermometers.
Unlike a temperature bath calibrator employing fluid as a medium, dry block calibrations employ a metal block as a source of clean, quick, and precise heating, which makes them find application in on-site and laboratory environments.

About Dry Block Temperature Calibrator
Dry Block Temperature Calibrator Working Principle
The operating principle of a dry block temperature calibrator involves a precisely controlled metal insert with pre-drilled holes/wells whose temperature increases or decreases by an internal mechanism.
This is how it works:
- A special metal block is heated/cooled using a PID controller heater.
- A high-precision reference sensor and controller are used to regulate heating.
- Temperature sensors like thermocouples or RTDs are placed within the wells.
- The calibrator is stabilized to maintain an accurate comparison and calibration setpoint.
This dry block temperature calibrator functions by removing contamination and fluid management, which makes it the ideal choice for calibration in both field and industrial settings.
Functions of a Dry Block Calibrator
The function of a dry block is to generate precise, repeatable temperatures allowing simultaneous testing of multiple sensors.
Key advantages:
- It eliminates oil, water, or another bath medium.
- Reduces contamination risk.
- Improves safety and mobility.
- Provides rapid heat-up and cool-down cycles.
- Simplifies on-site and lab-based calibration.
