9103, 9140, 9141 Field Dry-Well Calibrators
Highlights
Great performance in portable instruments
Lightweight and very portable
Accuracy to ±0.25 °C
RS-232 and Interface-it software included
Easy to recalibrate
If you’ve been using a dry well calibrator or dry block calibrator for field work, you know there’s a lot more to them than
temperature range and stability. Size, weight, speed, convenience, and software are also significant.
A field dry well needs to be portable, flexible, and suitable for high-volume calibrations or certifications. If it's not, you’ll soon
forget about the great stuff the sales rep told you and realize what you’ve really bought.
At Fluke Calibration, we use dry well calibrators every day in our manufacturing and calibration work, and we know what makes
a dry well easy and productive to use—which is exactly how users describe our series of field dry wells. These dry wells work
for you instead of the other way around.
Description
These three units beat every other comparable dry block calibrator in the industry in performance, size, weight, convenience,
ease of calibration, software, and price. In addition, the heating and cooling rate of each of these dry-well calibrators is
adjustable from the front panel, thermal switches can be checked for actuation testing, and multiple-hole inserts are available
for a variety of probe sizes.
Fluke Calibration dry wells are easy to calibrate. You don’t even have to open the case. This means less maintenance costs
and less down time when a dry well does need calibration.
Our Interface-it software lets you adjust set-points and ramp rates, log dry-well readings to a file, create an electronic strip chart,
and perform thermal switch testing with data collection. The software is written for Windows and has a great graphical interface.
Regardless of whether you want basic software or a completely automated calibration system, we’ve got what you want.
Every dry block calibrator we ship is tested at our factory, and every unit comes with a NIST-traceable calibration. There’s no
extra charge for the report, because we consider it an essential ingredient in our quality program. You shouldn’t have to pay
extra for calibration procedures we perform anyway.
9103
The 9103 covers below-ambient temperatures as low as –25 °C. The 9103 is stable to ±0.02 °C, and its display is calibrated to
an accuracy of ±0.25 °C at all temperatures within its range. In just eight minutes, 0 °C is reached, and 100 °C is reached in six
minutes, so your time is spent calibrating—not waiting.
The 9103 reaches temperatures 50 °C below ambient, so –25 °C is reached under normal ambient conditions. Our competitors
like to advertise their units as reaching –45 °C when they really mean –45 °C below ambient, which typically means it will go to
–20 °C. Our unit does not require you to work in a walk-in freezer to achieve its full advertised range.
Choose one of three removable
inserts sized for probes from 1/16
inch to 1/2 inch in diameter. Insert A
handles a full range of probe sizes
with a single well of each size. Insert
B features two wells each of 3/8, 1/4,
and 3/16 inches in diameter for
doing comparison calibrations.
Insert C has six 1/4-inch-diameter wells for multiple probe calibrations, and Insert D has three pairs of metric sized wells.
9140
1
The 9140 has a temperature range of 35 °C to 350 °C, and it reaches its maximum temperature in 12 minutes. At six pounds,
it’s small enough to easily carry in one hand. It’s truly a unique innovation in dry-wells.
The unit has a stability of ±0.05 °C or better and a uniformity of at least 0.4 °C in the largest-diameter wells and 0.1 °C in the
smaller wells. Despite its small size, this unit performs.
Use the display, calibrated to ±0.5 °C, as your reference, or use an external thermometer for maximum calibration accuracy.
With three removable inserts to choose from, the 9140 is as versatile as it is fast.
9141
Here’s an upright unit you’re going to love. It does calibrations up to 650 °C, weighs only eight pounds, and heats up to 650 °C
in only 12 minutes—12! This dry-well does everything but get legs and walk to the job for you. (And we’re working on one that
does that too.)
This four-inch-wide dry-well is amazing. You can control all functions from the front panel or hook it up to your PC with its built-
in RS-232 port. And just like the 9140, it works with all of our software described on page 80.
It has three removable well inserts available, an optional carrying case, a NIST-traceable calibration, and the best price in the
industry.
