Datasheet

1 RS-232 serial interface connector. For
PC communications, uploading and down-
loading data from memory and from the
probe INFO-CON connectors.
2 Sensor connector (PRT, thermocouple, or
thermistor)
4 External power adapter connection, for
continuous use without changing batteries.
Alternatively, 3 AA batteries will last more
than 20 hours in the field.
The 1523 Reference Thermom-
eters are versatile single-channel
thermometers that measure,
graph and record three sensor
types with one tool. Support for
PRTs/RTDs, thermocouples, and
thermistors provide flexibility to
choose the right probe for the job.
Two models let you make the
best choice for your application
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 is easy to see when the temperature
is stable (without statistics or long de-
lays) or to monitor processes over time
to verify correct operation.
Hold readings on the display at the
touch of a button, or document up to 25
readings and associated statistics for
easy retrieval. Statistics include the av-
erage maximum and minimum values,
and the standard deviation. View them
through the display or by uploading
it to a PC via RS-232 connection and
9940 I/O TookKit 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 avail-
able for those who prefer USB connec-
tors. 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.
INFO-CON connectors ensure
correct temperature conversion
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. The connector transfers this
information to the 1523/24 automati-
cally, 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 inter-
nal precision thermistor.
The new 1524 Reference
Thermometers help you do twice
the work in half the time. Two
channels and three sensor types
and high-speed measurement
make you more productive and
make model 1524 the one refer-
ence thermometer you need to
own. It has all the features
of the 1523, and it’s a data
logger too. A real-time clock and
memory for 15,000 time and
date stamped measurements
mean everything you are going
to need is in this package. Log
up to three times per second, or
once every hour or other options
in between. Download the data
to a PC for analysis when you
need it.
