Techne FWSP660M 660°C Secondary Standard Probe, 6mm, Including Case and Calibration Certificate

The Techne Secondary Standard Probes offer proven and reliable performance for your critical temperature measurements. The SSP660 can be used with the Tecal Accu-Temp high accuracy digital thermometer or any comparable unit. The SSP660 includes a hard carrying case and ITS-90 (NIST traceable) calibration certificate with coefficients. 

The SSP660 provides a higher level of accuracy and stability than the Techne WSP probes making it the ideal choice for use as a secondary standard reference thermometer.

Secondary standard 25 or 100 ohm SPRT diameter 1 / 4 inch x 18 inch long including handle. Includes hard carry case and ITS90 calibration certificate with coefficients. Calibrated Accuracy ±0.010 at 0°C. Calibrated range -196°C to 660°C.

660ºC Secondary Standard PRT

Model SSP670 PRTs are assembled using our special wire wound RTD elements and assembled into inconel sheaths. The SSP670 PRT has similar accuracy and long-term stability specifications you would find in much higher priced secondary standard PRTs.

The SSP670 PRT can be used as a working 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.
