Additel AccuMac AM1760 and AM1762 Secondary SPRTs
- Reliable SPRT for Daily Use
- Rtpw Drift: <4mK after 100hrs at 661°C
- Short-term Stability : <0.002°C at 0.01°C
- Temperature Range: -200°C to 670°C
- Inconel™ Sheath to Withstand Harsh Environments
- Fully Meets the ITS-90 Criteria for Reference Thermometers
- ISO 17025 Accredited Calibration Included
The AM1760 series Secondary SPRTs provides our customers with reliable secondary standards that can be used daily in their labs. These SPRTs feature an accuracy of <0.006°C at 0.01°C, a short term stability of <0.002°C and a very low drift rate of less than 0.004°C after 100 hours at 661°C. Two different lengths of these SPRTs are available at either12 inches (305 mm) or 20 inches (508 mm).
The sensing element is designed to protect the platinum sensing wire from contamination at high temperatures, giving these SPRTs a high level of stability and repeatability in performance. A uniquely designed support structure and filling material provides excellent balance between the hysteresis effect, mechanical shock and thermal shock performance.
This high performance probe fully meets the ITS-90 criteria for reference thermometers. Each probe comes standard with an ISO 17025 Accredited Calibration.
