Precision - related Considerations

• Temperature Accuracy and Stability: Look for furnaces with high accuracy and stability. For example, the Additel ADT850 has a stability of ±0.1 °C and radial and axial uniformities of ±0.25 °C at 1200 °C, which can ensure precise calibration results4. High - end models like the Fluke Calibration 9118A also offer excellent stability and uniformity, with temperature stability of ±0.1 degrees at 1200 °C, radial uniformity of ±0.25 degrees, and axial uniformity of ±0.2 degrees at the same temperature3.

• Uniformity: Good temperature uniformity is essential to ensure consistent calibration across all points. Some furnaces achieve this through multi - zone temperature control technology, which can independently control the temperature of different areas in the furnace to reduce temperature differences.

• Control System: A user - friendly control system with programmable temperature settings and data logging functions can improve calibration efficiency and convenience. It allows researchers to precisely set and control the calibration temperature and record relevant data for analysis and traceability.

Budget - related Considerations

• Initial Purchase Cost: Generally, well - known brand - name products with high precision tend to be more expensive. For example, the Additel ADT850 laboratory thermocouple calibration furnace starts at $20,8782. If the budget is limited, you can consider some products from domestic or emerging brands, but make sure to assess their quality and performance. Some manufacturers also offer customization services, which may be more cost - effective than buying high - end standard - model furnaces if the customization requirements are not too complex5.

• Operating Costs: This includes energy consumption, maintenance, and repair costs. Energy - efficient furnaces can save a significant amount of electricity costs in the long run. When it comes to maintenance and repair, choose furnaces from manufacturers that provide good customer support and maintenance services to reduce potential costs. Additionally, consider the lifespan of the furnace and its components. A longer - lasting furnace may have a higher initial cost but can be more cost - effective in the long term.
