Fluke Intros Benchtop Super-Thermometers
Super-Thermometer benchtop instrument.
Everett, WA — Fluke Corporation has introduced the 1594A/1595A Super-Thermometers from Hart Scientific, designed to combine accuracy, value and innovative features for calibration of SPRTs, PRTs and thermistors.

The new instruments are accurate enough for the primary lab, providing accuracy as good as 0.06 ppm (0.000015°C), and economical enough for the secondary lab. Metrologists can feel confident that every measurement made with the Super-Thermometer falls within expected limits, easily verified at any time. The 1594A and 1595A incorporate patent-pending "Ratio Self- Calibration" that enables users to test the accuracy or calibrate the resistance ratio linearity of the Super-Thermometer's measurement circuit regularly, easily, and without requiring any external devices or special training.

Now metrologists can verify accuracy and performance automatically in about 30 minutes, at the touch of a button. Although unlikely, measurement circuit defects would be detected and reported automatically.

Users can also calibrate the internal reference resistors using the resistance calibration function and an external standard resistor. The instrument assists with the calibration through an easy-to-use setup utility. Once the calibration is complete, the instrument reports the results to the display and provides the option to write the results to a USB memory device. The user can also choose to adjust the calibration parameters of the internal reference resistor by pressing the password-protected "Adjust Resistor" function key. In addition, new patent-pending design innovations incorporated into the Super-Thermometer reduce measurement noise and interference to levels that are unprecedented for a digital thermometry bridge. In a typical temperature calibration application, uncertainty due to measurement noise is as low as 0.00002C.

Super-Thermometers offer speeds as fast as one second per measurement (full accuracy with a two second sample rate). This means users can complete tests in less time, track temperature changes more accurately, and even evaluate thermal response in sensors. When measuring fixed-point temperatures that require the highest levels of accuracy and lowest levels of noise, users have complete control to change the measurement speed to meet their requirements.
