Fluke Australia is part of Fluke Corporation, a global leader in electronic test and measurement technology.
The company has introduced the new 1594A/1595A Super-Thermometers from Hart Scientific that are designed to combine accuracy, value and innovative features for calibration of SPRTs, PRTs and thermistors.
The Fluke 1594A and 1595A Super-Thermometers 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.
Key features include:
Ratio self-calibration for confidence in every measurement
The 1594A and 1595A feature 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.
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.
No other temperature measurement instrument on the market more fully empowers the metrologist to determine and improve instrument performance.
Calibrate internal reference resistors, quickly and easily
Users can also calibrate the Super-Thermometer’s internal reference resistors using the resistance calibration function and an external standard resistor. The Super-Thermometer assists with the calibration through an easy-to-use setup utility.
Once the calibration is complete, the Super-Thermometer reports the results to the display and provides the option to write the results to a USB memory device.
Low measurement noise
Measurement noise is caused by electrical noise and other random errors that can negatively influence measurement accuracy. 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 0.00002°C.
Fast measurement speed
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.
