Techne Secondary Standard Probe

Techne Secondary Standard Probe

Our Secondary standard probes offer proven and reliable performance for your critical temperature measurements. The SSP660 can be used with our Tecal Accu-Temp indicator or any comparable unit and the WSTC1450 with a higher accuracy 6 1/2 or 8 1/2 digit multimeter. The SSP660 includes a hard carrying case and ITS-90 calibration (NIST traceable) certificate with coefficients. The SSP660 gives a higher level of accuracy and stability than our WSP probes making it a good selection for use as a secondary standard reference thermometer. The WSTC1450 is assembled into a high purity alumina sheath for long term stability and accuracy. Calibration is supplied via a CD with an Excel spreadsheet containing polynomials for mV to temperature conversion.
