How will the 1523/24 save time and money?
Trending data and an intuitive interface make it
easy to decide, with little or no training, when
the temperatures are stable. High sample rates
mean quicker measurements. Fewer instruments
are needed since the 1524 connects two probes
and measures three sensor types. Finally, better
accuracy means less rework.
What functions does it support?
Statistics: Average, Stdev, Max, Min
Functions: Temperature, temperature difference
between channels, resistance, voltage
Is the calibration NIST traceable?
Calibrations for the probes and the readouts are all
NIST traceable. NVLAP accredited calibrations are
also available upon request. Some probes come
with accredited calibrations as standard.
What’s the difference between a NIST
traceable and NVLAP accredited calibration?
Most industries require calibration results to be
traceable to national standards. Sometimes there
is an additional requirement for an accredited
calibration certificate. Accreditation provides
assurance that an appropriate quality program is
in place and that training and procedures meet the
technical requirements for the service provided.
NVLAP is an accreditation body sponsored by
NIST and recognized and accepted throughout
the world. The Fluke Calibration temperature
calibration NVLAP Lab Code is 200348-0.
How should I choose a probe?
There are many choices in shape, size, and
dimension to fit your application. To begin, you
must know your temperature range and accuracy
requirements.
Thermocouples offer the widest temperature
range, and are especially useful for high tempera-
tures. However, they are usually the least accurate
temperature sensors.
PRTs provide the best combination of temperature
range and accuracy and are the most frequently
used reference sensor.
Thermistors are the most accurate secondary tem-
perature standards, with some approaching
the accuracy of a primary standard (SPRT).
However, thermistor temperature ranges are more
limited, often from 0 °C to 100 °C.
