You need accuracy for compliance, product yields, energy savings, and consistent results. The Fluke 1523 and Fluke 1524 use current reversal, a technique used in high-end instruments that eliminates thermal EMFs, for precision temperature measurements. Specifications are guaranteed from -10ºC - 60ºC ambient. Special precision resistors and a highly stable reference voltage source keep 1523 and 1524 accuracy virtually insensitive to environmental temperature.
The Fluke 1523 and Fluke 1524 Reference Thermometers from Fluke Calibration measure, graph, and record PRTs, thermocouples, and thermistors. These thermometer readouts deliver exceptional accuracy, wide measurement range, temperature logging, and trending, all in a handheld tool you can take anywhere.
The Fluke 1523 and Fluke 1524 let you handle field applications, laboratory measurements, and data logging with ease. And with the dual channel measurement capabilities of the model Fluke 1524, you can do twice the work in half the time.
Like all Fluke handheld tools, the 1523 and 1524 Reference Thermometers endure rigorous testing in temperature extremes and under harsh conditions of vibration, so you can take them anywhere you need to go.
