FLUKE 1594A Calibration Super-Thermometer
The Fluke Calibration 1954A Super-Thermometer stands out as a remarkable instrument designed for precision temperature measurements. It combines the accuracy of complex and expensive bridges with innovative features that simplify the measurement process, making it an excellent value for both primary and secondary laboratories. Capable of calibrating SPRTs, PRTs, and thermistors, the 1954A offers exceptional measurement accuracy, especially in resistance ratio measurements (Rx/Rs), with an accuracy as good as 0.2 ppm for typical thermometry ratios and 0.06 ppm for ratios near unity.
The Fluke 1954A Super-Thermometer internal reference resistors are enclosed in a temperature-controlled oven, ensuring stability and minimizing errors due to changing ambient conditions. Moreover, its low measurement noise, unprecedented measurement speed, and the patent-pending "Ratio Self-Calibration" feature empower metrologists to verify and maintain instrument performance easily. With user-friendly calibration functions and the ability to calculate the effects of self-heating, the 1954A Super-Thermometer is a versatile and powerful tool for precision temperature measurements.
Specifications for the FLUKE 1594A Calibration Super-Thermometer Include:
| Input Resistance Range | 0 to 500 kΩ |
| Display Resolution | 0.1 to 0.000001 |
| Sample Periods (seconds) | 1,2,5, and 10 |
| Ratio Range | 0 to 10 |
