Fluke 1594A Super-Thermometer Repair
The Fluke 1594A is a temperature calibration source or reference thermometer – built to hold or measure a temperature accurately enough that other instruments can be trusted against it.
Is your Fluke 1594A worth repairing?
Dry wells, baths and reference thermometers are long-life laboratory assets with high replacement cost. What fails is nearly always a heater, a stirrer, a control loop or a sensor – none of which is a reason to replace the instrument around them. Our answer for the Fluke 1594A: Repair. These are laboratory assets with a long life and replacement is rarely justified. We evaluate free of charge and quote before any work begins, and if the numbers do not favour repair we say so rather than quoting anyway.
What typically fails on the Fluke 1594A
- Well or insert damage.
- Heater or cooling element failure.
- Control loop instability – reaching setpoint but not holding it.
- Stability or uniformity outside specification – the specification that matters, and not visible on the display.
- Stirrer faults on liquid baths.
- Sensor or reference drift.
What you get back
Component-level repair rather than assembly swapping, verification against reference standards with the measured results documented, and a 90-day parts-and-labor warranty. Most instruments are back with you inside 5-10 business days.
