Investing in a temperature dry well calibrator requires balancing performance, cost, and usability. This guide outlines key considerations:
Temperature Range: Match it to your sensors—from -40°C (for cryogenic applications) to 700°C (for industrial ovens).
Uniformity and Stability: Look for specs like ±0.1°C uniformity across the well and <0.05°C/hour drift to ensure consistent results.
Well Size and Adaptability: Interchangeable inserts allow calibration of multiple sensor diameters (e.g., 3mm to 12mm).
Controller Features: Advanced models offer touchscreens, data logging, and USB/RS232 connectivity for audit trails.
Certification: Ensure compliance with ISO 17025 and traceability to ITS-90 standards for regulatory compliance. With these factors, buyers can avoid overpaying for unnecessary features or undershooting their calibration needs.
