Additel AccuMac AM1751 Secondary Reference PRT
- Affordable Reference Probe
- Temperature Range: -200°C to 670°C
- Accuracy: <0.012°C at 0.01°C
- Short-term Stability: <0.007°C
- Temperature Coefficient 0.003925 Ω/Ω/°C
- Fully Meets the ITS-90 Criteria for Reference Thermometers
- Inconel™ Sheath to Withstand Harsh Environments
- ISO 17025 Accredited Calibration Included
The AM1751 series of Secondary Reference PRTs offers affordable reference probes for precision temperature measurement and calibration both in the lab and in the field. These PRTs feature an accuracy of <0.012°C and a short term stability of <0.007°C.
To reach the best performance in stability and repeatability, the sensing element has been specially designed to protect the platinum sensing wire from contamination at high temperatures. A unique supporting structure and filling material provide the best balance among 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 Included.
Optional Accessories:
9070- Smart connector for reference PRT for use with Additel temeprature products
9071- Connector adapter from Additel smart connector to 4-wire with gold plated spades
9072- Connector adapter from Additel smart connector to 4-wire with clamps
Note: Carrying case included (Excludes Bend Probes)
