Fluke 7109A Specifications
6109A / 7109A
Portable Calibration Baths
Four times more
calibration throughput
with twice the accuracy
of Micro-Baths and
dry-block calibrators
Portable calibration baths designed
for clean process applications
Process manufacturing plants for pharmaceuticals, biotechnology, and food production utilize
many sanitary temperature sensors that require
regular calibration. Production must stop while
the calibrations are taking place. Therefore, more
calibration throughput means less plant downtime. And in businesses where even a few tenths
of a degree Celsius can cost thousands of dollars
in ruined product, temperature accuracy is crucial
to maintaining quality.
The Fluke Calibration 6109A and 7109A Portable
Calibration Baths let process industry professionals calibrate four times more sanitary sensors per
batch in less time and with twice the accuracy
of other baths in this class. Up to four tri-clamp
sanitary sensors fit easily into these baths for
calibration at ± 0.1 °C temperature display accuracy. Throughput is even higher for sanitary RTDs
with small or no flanges.
Two bath models cover a wide temperature
range: 35 °C to 250 °C for the 6109A and -25 °C
to 140 °C for the 7109A. Each model offers a “-P”
version that includes process electronics for connecting an external reference probe.
Professionals working in clean process industries,
including facilities managers, production engineers and calibration technicians, prefer these
baths for a variety of reasons.
Facilities managers who need to meet U.S. FDA
and ISO clean room standards like the baths’
stainless steel casing that stands up to harsh
cleaning solutions. They depend on the 6109A
and 7109A to help maintain the accuracy of the
plant’s temperature sensors, thus reducing the
possibility of an expensive product batch loss.
Production engineers also appreciate the baths’
accuracy, which helps them control sensor out-oftolerance conditions. Moreover, they prefer to use
a bath designed specifically for clean room calibration throughput. No more need to make do with
equipment designed for some other application.
Calibration technicians who perform calibrations
on platforms, in crawl spaces, and other hardto-reach parts of the plant enjoy the portability
and clean room compatibility (i.e. easy to sanitize,
don’t harbor bacteria) of these baths.
Global Fluke Calibration service and support
ensure that your 6109A and 7109A baths will
give you years of service that you can trust.

1
Tank – The stainless steel tank contains
the bath fluid.
2
Bath Fluid – Temperature sensors are
inserted into the bath fluid for calibration.
3
Control Sensor – A precision platinum
resistance thermometer (PRT) control
sensor measures and controls the temperature of the bath fluid.
4
Stir Motor Cover – Protects the stir motor.
5
Stir Motor (under the Stir Motor Cover) –
Drives the propeller that circulates the fluid
to produce a uniform temperature.
6
Stir Guard – Separates the working area
of the tank from the stir propeller. MIN and
MAX marks show the correct fill levels.
7
Propeller – Stirs the bath fluid.
Ready Indicator – Changes from amber to
8
green when the bath fluid temperature has
settled at the setpoint. Green indicates the
bath is ready to begin measuring.
Carrying Handle – Use the carrying
9
handle to lift or move the bath. There are
also recessed handles on the side of the
bath (not shown).
Threaded Holes – Used to attach
10
accessories to the bath.
Tank Cover – Isolates the bath fluid from
11
the environment, reduces fumes, prevents
objects from falling into the tank, and
keeps the fluid temperature stable.
