Low Temperature Calibration Source
Temperature calibration down to −115 °C – without a liquid bath.
Working below −80°C brings a different set of challenges. Liquid baths can deliver the performance, but add complexity in handling, portability and daily operation.
The Isotech Model 526 offers another approach. Using Free Piston Stirling Cooler (FPSC) technology, this compact 12 kg dry block calibrator combines ultra-low temperature capability with the stability and uniformity required for professional calibration — suitable for both lab and field use.
Key performance:
- Temperature range: −115°C to +50°C
- Stability: ±0.03°C across the full range
- Resolution: 0.01°C
- Cooling from ambient to −115°C in approximately 85 minutes
- Typical stabilisation time of approximately 15 minutes
- Radial uniformity: <0.03°C
- Weight: only 12 kg
- Meets the requirements of EURAMET cg-13
