And with the dual channel measure- ment capabilities of the model 1524, you can do twice the work in half the time. Make accurate, consistent measurement...anywhere You need accuracy for compliance, prod- uct yields, energy savings, and consistent results. The 1523/24 uses current reversal, a technique used in high-end instruments that eliminates thermal EMFs, for precision temperature measurements. Specifications are guaranteed from 10 C to 60 C ambient. Special precision resistors and a highly stable reference voltage source keep 1523/24 accuracy virtually insensi- tive to environmental temperature. Like all Fluke handheld tools, the 1523/24 Reference Thermometers endure rigorous testing in temperature extremes and under harsh conditions of vibration, so you can take it with confidence anywhere you need to go. An optional magnetic hanger allows you to hang the thermom- eter for easy viewing while freeing your hands to focus on the job.

You can change the graphs resolution at the touch of a button. Now it is easy to see when the temperature is stable (without statistics or long de- lays) or to 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.
