The 1523/24 Reference Thermometers from
Fluke Calibration 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.
Finally, a reference
thermometer as
versatile as you
You need accuracy for compliance, product
yields, energy savings, and consistent results.
The 1523/24 uses current reversal, a technique
used in high-end instruments that eliminates
thermal EMFs, for precision temperature mea-
surements. Specifications are guaranteed from
–10 °C to 60 °C ambient temperature. 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 1523/24
Reference Thermometers endure rigorous testing
in temperature extremes and under harsh condi-
tions of vibration, so you can take it 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.
Monitor trends in
the lab or in the field
See trends graphically on the 1523/24
thermometer’s 128x64 backlit LCD display.
You can change the graph’s resolution at the
touch of a button. Now it’s easy to see when the
temperature is stable, without statistics or long
delays, or monitor processes over time to verify
correct operation.
Document on demand up to 25 readings and
associated statistics for easy retrieval. You can
view the data through the display or by upload-
ing it to a PC via RS-232 connection and 9940
software, included free. To monitor and log more
data over time, use a PC and optional LogWare II
software.
RS-232-to-USB adapters are available for those
who prefer USB connectors. Battery power lasts
at least 20 hours on three AA batteries, or use
the dc power adapter for extended periods of
measurement. Power saving features can be
enabled or disabled for longer battery life or
greater convenience.

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
• 128x64 backlit LCD graphic display
• Plot and scale trends in real time
• Simultaneous dual channel readings
Inside the INFO-CON, a memory chip keeps
calibration information for the attached probe.
Simply plugging in the probe uploads the
information to the readout, ensuring the correct
temperature conversion for accurate, hassle-free
measurements.
Probes may be locked by password to specific
channels and readouts for security or for system
calibration traceability. Plug any thermocouple
with mini-thermocouple jacks into an optional
universal thermocouple adapter for convenient
measurement. Each thermocouple adapter or
standard connector supports reference junction
compensation (RJC) with its own internal preci-
sion thermistor.
Make accurate, consistent
measurements–anywhere.
