Fluke Calibration 1523/1524 Handheld Thermometer Readout

The 1523/24 Reference Thermometers from Fluke’s Hart Scientific Division measure, graph, and record PRTs, thermocouples, and thermistors. These thermometer readouts deliver exceptional accuracy, wide measurement range, logging, and trending, all in a handheld tool you can take anywhere.
The 1523/24 lets you handle field applications, laboratory measurements, and data logging with ease. And with the dual channel measurement capabilities of the model 1524, you can do twice the work in half the time.

Three sensor types

  • PRTs: –200 °C to 1000 °C
  • Thermocouples –200 °C to 2315 °C
  • Precision thermistors: –50 °C to 150 °C

Accuracy

  • PRTs: up to ±0.011 °C
  • Thermocouples : ±0.24 °C for J,K,L,M
  • Precision thermistors: ±0.002 °C

Fast mode

  • PRTs: 0.45 seconds per sample
  • Thermocouples: 0.3 second per sample
  • Precision thermistors: 0.3 seconds per sample

Two models

  • 1523: Single channel standard model; memory for 25 readings and statistics
  • 1524: Two channels; memory for logging 15,000 measurements; real-time clock for time and date stamps

Graphical display

  • 128×64 backlit LCD graphic display
  • Plot and scale trends in real time
  • Simultaneous dual channel readings
