The Techne range of PRT offer proven and reliable performance for your critical temperature measurements. They can be used with the Tecal Accu-Temp high accuracy digital thermometer or any comparable unit. All PRT models include a carrying case and ITS-90 (NIST traceable) calibration certificate with coefficients and resistance / temperature table.
WSP350 and WSP425
The Techne Working Standard Probes are an ideal choice for use in verifying, calibrating and monitoring the temperature of calibration baths, furnaces, precision fluidised baths, Dri-block calibrators, incubators, freezers, water baths, thermal validation systems, comparison calibrations of other sensors or for any other temperature application where a high level of accuracy and reliability are required.
All probes shown are fully annealed to remove any instability for longer term accuracy and performance throughout the operating range. Working standard 100 ohm PRT diameter 1 / 4 inch x 12 inch long with hard carrying case including ITS90 calibration certificate with coefficients. Calibrated Accuracy ±0.025 at 0°C. Calibrated range -50 to 350°C or 425°C.
