RTD Probes
The Techne model WSP425 and SSP670 PRTs are an excellent choice for use as reference sensors in all types of systems, including dry block calibrators, liquid calibration baths, ovens, reactors and other applications where temperature needs to be accurately measured.
Our PRTs off er proven and reliable performance for critical temperature measurements. They can be used with our Tecal Accu-Temp indicator or any comparable unit. Both models include a carrying case and ITS-90 calibration (NIST traceable) certifi cate with coeffi cients and resistance vs. temperature table. The SSP670 has excellent performance, specifications and wide temperature range at an aff ordable price, while the WSP425 is designed for measurements within a narrower temperature range.
670°C Secondary Standard PRT
Model SSP670 PRTs are assembled using our special wire wound RTD elements and assembled into inconel sheaths. The SSP670 PRT has the accuracy and long-term stability specifications you would find in much higher priced secondary standard PRTs.
The SSP670 PRT can be used as a secondary standard in calibration baths, furnaces, fluidized baths, dry block calibrators and other any other temperature calibration work requiring a high level of accuracy and repeatability.
Calibration
Each SSP670 includes an ITS-90 NIST traceable calibration with a+, b+, c+, a- and b- coefficients and R vs T table. A carrying case is also included.
