The Fluke 1523 / 1524 are high-precision handheld reference thermometers for laboratory and field use, compatible with three core temperature sensors: PRTs, thermocouples and precision thermistors. Adopting current reversal technology exclusive to high-end instruments, it eliminates thermal EMF interference to deliver ultra-precise readings, stable operation across ambient temperature from -10 ℃ to 60 ℃.

1523: Single-channel standard model, stores 25 readings with statistical calculation function;

1524: Dual-channel professional model, supports simultaneous dual-channel measurement, built-in real-time clock for time-stamped logs, up to 15,000 recorded datasets and real-time trend graph plotting. Ideal for temperature calibration, production line comparison and laboratory constant temperature verification.

Equipped with backlit graphic LCD, Data Hold, Min/Max statistics and auto sampling logging. Optional magnetic hanger frees hands for operation. RS232 communication port included for data export, widely applied in metrology calibration, pharmaceutical, food processing, HVAC and industrial temperature quality inspection.
