Fluke Hart Scientific 9173 Series Dry-Well Temperature Calibrator
Fluke Hart Scientific 9173 Metrology Dry-Well Calibrator (50 °C to 700 °C)
The Fluke HART SCIENTIFIC Model 9173 provides a calibration range of 50 °C to 700 °Cwith a
calibrated display accurate to ±0.25 °C at 665 °C. In addition to
exceptional accuracy, the 9173 is
stable from ±0.005 °C to ±0.03 °C,
depending on temperature. With
203 mm (8 in) of immersion, the
9173 significantly reduces stem
conduction errors at high-temperatures.Just like the 9172, this dry-well
has exceptional axial and radial
uniformity. Stability and
uniformity performance of this unit
are enough to dramatically reduce
uncertainty budgets for calibrations
of thermometers at high
temperatures.
Fluke Hart Scientific 9173 Metrology Dry-Well Calibrator Establishes New Boundry in Accuracy
Every once in a while, a new
product comes around that
changes the rules of the game. It happened
when Fluke Hart Scientific introduced handheld
Dry-Wells. It happened when Fluke Hart Scientific introduced Micro-Baths. Now
Fluke Hart Scientific has combined Bath-Level performance
with Dry-Well functionality
and legitimate reference thermometry
to create Metrology
Wells.
With groundbreaking new proprietary
electronics from Fluke’s
Hart Scientific Division (patents
pending), Metrology Wells let you
bring lab-quality performance into
whatever field environment you
might work in. New analog and
digital control techniques provide
stability as good as ±0.005 °C.
And with dual-zone control, axial
(or “vertical”) uniformity is as good
as ±0.02 °C over a 60mm
(2.36 in) zone. (That’s 60 mm!)
Such performance doesn’t exist
anywhere else outside of fluid
baths.
In short, there are six critical
components of performance in an
industrial heat source (which the
European metrology community
explains, for example, in the document
EA-10/13): calibrated display
accuracy, stability, axial (vertical)
uniformity, radial (Well-to-Welll)
uniformity, impact from loading,
and hysteresis. Fluke Hart Scientific added a seventh
in the form of a legitimate
reference thermometer input and
created an entirely new product
category: Metrology Wells.
(By the way, Metrology Wells are
the only products on themarket
supported by published specifications
addressing every performance
category in the EA-10/13.
Our specs aren’t just hopes or
guidelines. They apply to every
Metrology well sold by Fluke Hart Scientific.
Fluke Hart Scientific Metrology Wells Optionally Offer Built-In Reference Thermometry for Enhanced ACcuracy
Fluke’s Hart Scientific Division has been
making the world’s best thermometer
readout devices for quite some time. Our
Super-Thermometer, Black Stack, and
Tweener thermometers are well-known
everywhere. Now we’re making our proprietary
Tweener measurement circuitry
available directly in a heat source — our
new Metrology Wells.
This optionally built-in input accepts
100-, 25-, and 10-ohm PRTs. It reads
thermometer probes accurately from
±0.006 °C at 0 °C to ±0.027 °C at 661 °C,
not including errors from the probe. It is
compatible with every PRT sold by Hart
and connects to Metrology Wells via a
5-pin DIN connector.
Two things dramatically differentiate
the Tweener circuit from the measurement
electronics built into many
dry-wells. First, it accepts unique
ITS-90 characterization coefficients
from reference thermometers, which
allow you to take full advantage of the
accuracies of those thermometers. Secondly,
it comes with a traceable, accredited
calibration, providing you full
confidence in the integrity of its
measurements.
Nothing beats a Hart Scientific Metrology Well
for industrial thermal performance.
And nothing beats a Tweener measurement
for built-in reference
thermometry. When ordering be sure to specify ( -R) with the insert of choice in the model number, e.g. 9173-B-R.
Great Features Offered by the Fluke Hart Scientific 9173
A large LCD display, numeric keypad,
and on-screen menus make
use of Metrology Wells simple and
intuitive. The display shows the
block temperature, built-in reference
thermometer temperature,
cutout temperature, stability criteria,
and ramp rate. The user interface
can be configured to display
All four models come with an
RS-232 serial interface and the
Model 9930, Interface-it software.
All are also compatible with Model
9938 MET/TEMP II software for
completely automated calibrations
of RTDs, thermocouples, and
thermistors (Metrology Wells with
built-in reference input options
will be compatible with
MET/TEMP II in early 2006).
Even without a PC, Metrology
Wells have four different preprogrammed
calibration tasks that allow
up to eight temperature set points with “ramp and soak” times
between each. There is an automated “switch test” protocol that
zeros in on the “dead-band” for
thermal switches. And a dedicated °C/°F button allows for easy
switching of temperature units.
Any of six standard inserts may
be ordered with each unit, accommodating
a variety of metric- and
imperial-sized probe diameters. And Metrology
Wells are small enough and light
enough to go anywhere.
Fluke's Field Metrology 9173 Metrology Dry-Well Calibrator display is calibrated with high-quality traceable and accredited PRTs. Each device (process and non-process versions) comes with an IEC-17025 NVLAP-accredited calibration certificate, which is backed by a robust uncertainty analysis that considers temperature gradients, loading effects, and hysteresis. Fluke's 9173 has a display accuracy of ± 0.25 °C at 665 °C. Each calibration is backed with a 4:1 test uncertainty ratio.
Fluke-Hart Scientific 9173 Dry-Well Calibrator offers 6 Removable Dry-Fluke Hart Scientificll Inserts
Choose one of six removable inserts sized for most of the common sensor probes from 1/16 inch to 1/2 inch in diameter. Additional inserts may be ordered for backup capability to accommodate other size temperature sensors:
