Fluke 1552A Ex Stik Thermometer Repair
The Fluke 1552A (Ex Stik) is a reference thermometer — an intrinsically safe stick-style digital thermometer with a built-in PRT probe that reads temperature to high accuracy for field reference and calibration use, the updated companion to the 1551A. Its accuracy lives in the PRT probe and the measurement reference, which is where service and calibration focus.
FlukeServiceCenter.com repairs and calibrates the Fluke 1552A for calibration labs, pharmaceutical QA, and process engineers.
Common Fluke 1552A problems we fix
