Accuracy is paramount in temperature calibration. Look for a dry block calibrator with high accuracy specifications, typically within ±0.1°C or better. Stability is also crucial, as it ensures that the calibrator maintains a consistent temperature over time. Models with advanced PID controllers and high-quality insulation offer better stability.
Block Size and Configuration
The size and configuration of the metal block determine the number and type of sensors that can be calibrated simultaneously. Consider the dimensions of your temperature sensors and choose a block with holes that can accommodate them. Some blocks have multiple holes of different sizes, allowing for the calibration of various sensor types.
Portability
If you need to perform calibrations in the field or at multiple locations, portability is an important consideration. Look for a dry block calibrator that is lightweight, compact, and easy to transport. Battery-powered models offer added flexibility, eliminating the need for a power outlet.
Connectivity and Data Logging
Modern dry block calibrators often come with connectivity options, such as USB, Ethernet, or wireless, allowing for easy integration with computers and other devices. Data logging capabilities enable you to record calibration data for analysis and documentation. Consider these features if you need to manage and analyze calibration results.
