What's New at Hart
|
Announcing,
the new Field Metrology Wells with automated calibration of temperature
sensors, transmitters and switches – in a compact attractive package
from your friends at the Fluke Hart Scientific division. Find out how to
get yours today.
Temperature calibration has never been so easy. With Field Metrology
Wells from Hart Scientific you simply:
1)Put the probe into the Field Metrology Well
2) Set up the test or calibration
3) Run it
4) Come back later and review the results.
There’s no babysitting, no extra software to buy, no manually
recorded results and no need to repeatedly move each step of the
calibration along. The results are documented and you can view them when
you return or download them to a computer.
The 9140 series Field Metrology Wells are designed to meet key
performance criteria over the temperature range of –25 °C to 661
°C. With three models to choose from you can maximize performance in a
way that fits into your budget.

You know what’s at stake. It costs thousands to shut down a
production line for maintenance and more if the shutdown is unplanned.
The credibility of a technician’s recommendation to shut down is only as
good as his infrared thermometer and its calibration. Two major
requirements are accuracy and consistency.
How to get accurate and consistent results: Even those infrared
thermometers that cannot be adjusted can benefit from a calibration that
demonstrates the consistency and validity of your results. A trusted
calibration means less worry, fewer questions and more time being
productive. To get more reliable, traceable, and consistent results, buy
a 4180 or 4181 Precision Infrared Calibrator. Consistent and accurate
calibrations require large targets because of scatter in infrared
thermometer lenses. Reliable calibration of the measurement surface
measures the energy radiated by the surface and not just its internal
temperature. Called “radiometric calibration,” it calibrates the
infrared temperature of the target which depends on emissivity (the
largest and most neglected source of error in infrared temperature
calibrations). Click here for an informative application note. These
easy-to-use infrared calibrators are high-accuracy, portable and
compensate for the emissivity of infrared thermometers in a simple way
with unique technology. Model 4180 has a temperature range of –15 °C to
120 °C, with radiometric display accuracy as good as ± 0.40 °C, and
Model 4181 measures from 35 °C to 500 °C, with radiometric display
accuracy as good as ±0.35 °C. Click

With a 7380, Automated Calibration System, you can perform
consistent, repeatable calibrations quickly and efficiently.
Each system comes complete with everything you need to automate the
calibration of PRTs, thermistors and thermocouples, including a 7380
bath for calibrations from 100 °C down to –80 °C, a 5615 Secondary
Reference Probe, and a 1529 readout that can measure up to four
temperature sensors. A 9938 MET/TEMP II automation package is included
to minimize labor costs and maximize return on investment. |
The 5608 and 5609 are affordable high-temperature secondary reference
PRTs. The temperature range of the 5609 goes from –200 °C to 670 °C,
with optional calibrations. Its short-term stability at the triple point
of water is only ± 10 mK, and its one-quarter-inch (6.23 mm) diameter
lets you get accurate measurements in only 100 mm of immersion.
The 5608 is also a ± 10 mK probe at the triple point of water, but
its one-eighth-inch (3.18 mm) diameter makes accurate measurements from
–200 °C to 500 °C possible with only 80 mm (3.1 in) of immersion. With
multiple sheath length options on both of these probes, you’ll find the
dimensions that are just right for your specific application. |
Hart Scientific, a division of Fluke Corporation and the world leader
in temperature calibration products and services, announces the new Hart
Scientific 1620A paperless temperature and humidity data logger with
wireless, Ethernet, and RS-232 communications. |
The 5947 Mini Metal-Cased Aluminum Cell completes Hart’s set of
metal-cased fixed-point cells that spans from 29.7646 °C to 660.323 °C.
These cells meet the requirements of the ITS-90 and also overcome the
fragility of the classic quartz fixed-point cells. If you’re calibrating
working SPRTs, PRTs, or thermocouples and want the most accurate
calibration possible, these cells will give it to you.
These mini cells can achieve nearly the same uncertainty levels as
Hart’s traditional fixed-point cells, but Hart’s 594X series of mini
cells cost less, work faster, and are easier to use than traditionally
sized cells because they can be used in our 9260 Mini Fixed-Point Cell
Furnace. The 5947’s immersion depth is 156 mm (6.14 in), and the
diameter of its reentrant well is 7.8 mm (0.31 in). |
The 5611T Teflon Probe’s unique construction makes it an especially
versatile thermistor. With a tip that is just 3 mm (0.120 in) in
diam¬eter and a Teflon coating that makes it impervious to most liquids,
the Teflon Probe is handy for measuring in a wide variety of
applications, including bio-pharmaceuticals. It’s even immersible to
nearly 20 feet and very flexible.
The 5611T’s thermistor bead is encapsulated in a mylar sleeve that is
encapsulated inside a Teflon sleeve. The Teflon sleeve is melted around
the Teflon-insulated cable, forming a moisture-proof seal.
The 5611T’s has low self heating, fast response times, and is less
susceptible to mechanical shock than a PRT. |
Fluke’s Hart Scientific Division, the world leader in temperature
calibration, announces new triple point of water cells. The triple point
of water occurs when water coexists within a single glass enclosure
(typically glass) in all three of its phases: gas, liquid, and solid. It
is defined within the International Temperature Scale as 0.01°C and is
the most accurate device used to calibrate or verify thermometers.

Offer stability to ±0.005 °C and axial (vertical) uniformity to ±0.02 °C
Every once in a while, a new product comes around that changes the
rules. It happened when we introduced handheld dry-wells. It happened
when we introduced Micro-Baths. Now we’ve combined bath-level
performance with dry-well functionality and legitimate reference
thermometry to create Metrology Wells. |
