Calibration, loop checking, conformance testing,
troubleshooting, maintenance, and repair are
some of the varied duties that need a 1523/24
thermometer. Use it for a handy temperature
reference in baths, dry-block calibrators,
thermowells, clean rooms, engines, heat
exchangers, furnaces, freezers, or anything else
that must be calibrated, checked, or maintained.
Calibration
Tolerances of RTDs, thermocouples, transmitters
and temperature controllers improve over time.
Calibrations determine which instruments to
accept against their tolerances. If you make
comparisons to an inaccurate reference
standard, the risks of false accept and false
reject increase. Test uncertainty ratios (TURs)
that keep the reference four times more accurate
than the test unit greatly reduce this risk. The
1523/24 lets you get better TURs on a wider
range of workload.
The 1523/24 can also help boost cal lab pro-
ductivity with fast sample rates and dual chan-
nel measurement. Accurately measure up to
seven samples per second, or calibrate two sets
of workload at the same time, with the two ref-
erence channels.
Test and measurement
Testing the performance of internal and
external combustion engines, turbines, steam
systems, cooling towers, heat exchangers,
and refrigeration systems requires measuring
differences between inlet and outlet
temperatures. The 1524 can simultaneously
measure, calculate and record these differences.
The high sampling rate and logging capability
of the 1524 make it easy to determine the
response time of temperature sensors. In
addition, graphing in the 1523/24 makes it
easy to see temperature trends in a system and
quickly identify stability.
With a precision thermistor in stainless steel
or Teflon coating, the 1523/24 combines
laboratory accuracy with speed, reliability,
and intuitive measurement. And forget about
waiting 20 minutes for equilibration; you can
see graphically when the temperature trend is
stable.
1523 single-channel thermometer
The 1523 Reference Thermometer is a versatile
single-channel thermometer that measures,
graphs and records three sensor types with one
tool. Support for PRTs/RTDs, thermocouples, and
thermistors provide flexibility to choose the right
probe for the job.
1524 two-channel thermometer
The new 1524 Reference Thermometer helps
you do twice the work in half the time. Two

Logging and validation
Whether you are testing a product, validating
a process, troubleshooting or doing research,
multi-channel logging with the 1524 can help
you get the data you want, where, how and
when you want it. Gather data independently of
a computer. If space is a limitation, the compact
size of the 1524 is ideal. In addition, you can
choose your sample rate, monitor values in real
time, directly transfer data to a computer, and
record up to 15,000 time and date stamped
measurements.
