Fluke Hart Scientific 1523-156 Reference Thermometer with Probe

  • 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 -10 ºC to 60 ºC ambient. Special precision resistors and a highly stable reference voltage source keep 1523/24 accuracy virtually insensitive to environmental temperature.

    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.
