RTD Probes
The Techne model WSP425 and SSP660 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) certificate with coefficients and resistance vs. temperature table. The SSP660 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.
The model WSP425 has a calibrated operating range of -50 to +425°C, and the model SSP660 from -80 to +660°C.
425°C Working Standard PRT
The model WSP425 PRT is a great choice when lower temperature range is required.
The sheath is of stainless steel construction with a strain free wire wound .3924 alpha sensing element.
The WSP425 PRT can be used as a working standard in calibration baths, furnaces, fluidized baths, dry block calibrators or for any other temperature calibration work.
Combine it with our model Tecal Accu-Temp RTD indicator for a system with high overall accuracy. The WSP425 PRT includes a NIST traceable ITS-90 calibration with coefficients and R vs T table.
Calibration
Each WSP425 PRT includes an ITS-90 NIST traceable calibration with a+, b+, a- and b- coefficients and R vs T table. A padded carrying case is also included.
