Fluke 1523 Reference Thermometer

Please Note: Probes are not included with the basic instrument.

The Fluke 1523 Reference Thermometer from Fluke Calibration measures, graphs, and records PRTs, thermocouples, and thermistors. These thermometer readouts deliver exceptional accuracy, wide measurement range, logging, and trending, all in a handheld tool you can take anywhere.

The Fluke 1523 is a versatile single-channel thermometer that measures, graphs and records three sensor types with one tool. Support for PRTs/RTDs, thermocouples, and thermistors provides flexibility to choose the right probe for the job.

See trends graphically on the 1523 thermometers' 128 x 64-backlit LCD display. You can change the graph’s resolution at the touch of a button. Now it’s easy to see when the temperature is stable, without statistics or long delays, or monitor processes over time to verify correct operation.

Hold readings on the display at the touch of a button, or document up to 25 readings and associated statistics for easy retrieval. Statistics include the average maximum and minimum values, and the standard deviation. View them through the display or by uploading it to a PC via RS-232 connection and 9940 I/O TookKit software, included free.

Applications

Calibration, loop checking, plant startup, troubleshooting, maintenance, and repair are some of the varied duties that need a 1523 thermometer. Use it for a handy temperature reference and temperature logger in baths, dry-block calibrators, thermowells, clean rooms, engines, heat exchangers, furnaces, freezers, or anything else that must be calibrated, checked, or maintained.
