Fluke Calibration 1523 Handheld Thermometer

Fluke Calibration 1523 Handheld Thermometer

You need accuracy for compliance, product yields, energy savings, and consistent results. 1523 uses current reversal, a technique used in high-end instruments that eliminate 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 the 1523 accuracy virtually insensitive to environmental temperature.

Like all Fluke handheld tools, the 1523 Reference Thermometers endure rigorous testing in temperature extremes and under harsh conditions of vibration, so you can take them anywhere you need to go.

An optional magnetic hanger allows you to hang the thermometer for easy viewing while freeing your hands to focus on the job.
