FLUKE Secondary PRT with Calibration Options – 5608 and 5609
The 5608 comes with a one-eighth inch (3.18 mm) diameter sheath in lengths of 9 inches or 12 inches. The 5609 comes with a one-quarter inch (6.35 mm) diameter sheath in lengths of 12 inches, 15 inches, and 20 inches; or with a 6 mm diameter in lengths of 300 mm, 400 mm, or 500 mm.
When looking for improved response time and reduced stem effect in shallow immersion, look for small diameter probes, because the measurement error called stem effect is caused by the diameter of the stem rather than the length of the stem.
Both of these probes have Inconel™ sheaths and are made using a special manufacturing process, giving them great precision over a wide temperature range. The sensors for these probes are reference-grade platinum and feature four-wire connections with less noisy measurements than two-wire counterparts.
As standard, each probe includes its resistance value at the triple point of water. If calibration is desired, you can order a NVLAP-accredited calibration from our laboratory; lab code 200348-0. On the report of calibration, you’ll get the test data and the ITS90 calibration coefficients that you can easily input into any Fluke Calibration thermometer. If you order your probe with an smart connector, we’ll program the coefficients directly into your connector, which loads the coefficients for you when you plug it into our 1524 Handheld Thermometer.

Temperature Calibrators
FLUKE Calibration 6109A / 7109A Portable Calibration Baths
Four times more calibration throughput with twice the accuracy of Micro-Baths and dry-block calibrators
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-of-tolerance 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 hard-to-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.
Calibrate more sanitary sensors at a time – with confidence
The 6109A and 7109A baths calibrate most temperature sensor applications used in clean process manufacturing, including pharmaceutical bioreactors (-10 C to 100 °C), chemical reactors (200 °C), steam-in-place process (122 °C to 140 °C), autoclave sterilization (120 °C to 135 °C), food storage freezers (-25 °C), and food processing (0 °C to 220 °C).
A large tank volume (112 mm square tank opening x 154 mm depth) lets you immerse up to four sanitary sensors at the same time. Calibrate a batch of odd shaped sensors of varying lengths and diameters, and still have room for a reference thermometer. Fast heating and cooling times let you get the job done without spending a lot of time waiting for the bath to come to temperature and stabilize. Increase your sanitary sensor calibration throughput and decrease expensive production downtime.
Excellent system display accuracy of ± 0.1 °C. Accuracy covers all sources of error including calibration uncertainty, stability, uniformity, and repeatability. NVLAP accredited calibration is included standard. Fluke Calibration’s high metrological standards and conservative specifications mean you can have confidence in the measurements you make with the 6109A and 7109A Portable Calibration Baths.
Take these portable baths almost anywhere, including the clean room
The 6109A weighs 16 kilograms (35 pounds) and the 7109A weighs 20 kilograms (44 pounds). They each feature a fixed, non-rotating bail handle, enabling most people to carry a bath with one hand. Single-handed carrying comes in handy when the job includes walking up and down stairs, across catwalks, and into other hard-to-reach environments. Two recessed handles on the bottom of each bath also make it easy to move from a shelf to a cart or benchtop. A sealed lid protects against fluid spills while moving the bath.
Stainless steel casing stands up to the harsh chemicals used to sterilize equipment for clean room use. Synthetic materials used for decals, keypads and feet do not harbor bacteria. The keypad is sealed against moisture ingress to protect against damage during cleaning or in non-controlled environments.
Easy to use and maintain
Each bath features a large color display that indicates date and time, bath fluid temperature, setpoint temperature, control indicator when the fluid is at setpoint, and heating status. A ready indicator changes color from amber to green, giving you 360-degree visual indication when the bath fluid has reached its setpoint temperature and is ready for you to start making measurements.
A hot warning indicator lights up if the fluid temperature reaches above 60 °C, warning the operator that the bath fluid and tank area are hot and should not be touched.
An adjustable probe fixture holds up to four tri-clamp sensors securely inside the tank opening during calibration. An optional single probe clamp kit holds a reference probe.
Fluid spills create mess and potential safety hazards. The 6109A and 7109A include an overflow tube that directs excess bath fluid into an optional overflow container. A drain tube makes it easy to remove bath fluid for replacement or transport.
