Features and Benefits
These three units beat every other comparable dry-well 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-wells 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.
Hart 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 they do 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-well 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.
Model 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.
Model 9140
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.
Model 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.
It has three removable well inserts available, an optional
carrying case, a NIST-traceable calibration, and the best price in
the industry. |
