  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.

  I own a Fluke Calibration Micro-Bath. Why do I need a 6109A or 7109A bath?

  If you already own a Fluke Calibration Micro-Bath or dry-block calibrator, thank you for being a customer! We hope you are enjoying the portability and stability of these popular products.

  However, there are a few reasons why you should consider adding a 6109A or 7109A bath:

  Errors of just a few tenths of a degree Celsius can cause expensive losses in ruined product. The 6109A and 7109A baths are twice as accurate as a Micro-Bath, helping you to reduce this risk. The 6109A and 7109A have four times the calibration throughput of a Micro-Bath, which can only calibrate a single tri-clamp sensor at a time. They’re made with materials that don’t harbor bacteria. Their stainless steel panels and tank are easy to clean and rust resistant–perfect for clean room use. We hope you will continue to use your Fluke Calibration Micro-Bath for many years to come. The 6109A or 7109A baths will also serve you well if you need the throughput, accuracy, and clean room readiness that they provide.

  Temperature Calibrators

  FLUKE Calibration 6102/7102/7103 Micro-Bath

  Portable and extremely stable

  Need portability and extreme stability? Fluke Calibration Micro-Baths have both. We invented the Micro-Bath. And, while many have tried to duplicate it, none of them use proprietary Fluke Calibration controllers, so none of them deliver performance like a Fluke Calibration bath. Micro-Baths can be used anywhere for any type of sensor. The 6102 weighs less than 4.5 kg (10 lb.), with the fluid. It’s lighter and smaller than most dry-wells, has a spill-proof lid, and is easier to carry than your lunch. You can take it where you need to go without carts or excessive effort. Micro-Baths can even be transported with the fluid in them.

  Wherever you go with your Micro-Bath, you can count on its performance. Each model is stable to ±0.03 °C or better, depending on the fluid you use. Uniformity is ±0.02 °C or better for low uncertainties using a reference thermometer. Display accuracy has been improved to ±0.25 °C for quick calibrations without a reference thermometer. In short, you get the stability and precision of a liquid bath in a dry-well-sized package. Don’t be fooled by competitors who pour oil into a dry-well and call it a bath. Micro-Baths are maximized for true fluid-bath performance.

  With a 48 mm (1.9-inch) diameter, 140 mm (5.5-inch) deep tank, a Micro-Bath can calibrate any type of sensor including short, square, or odd-shaped sensors. The problems of fit and immersion are virtually eliminated by using a fluid medium rather than a dry-block calibrator. Micro-Baths are perfect for liquid-in-glass and bimetal thermometers.

  The 6102 has a temperature range from 35 °C to 200 °C, the 7102 covers –5 °C to 125 °C, and the 7103 extends from –30 °C to 125 °C. Stability, uniformity, and accuracy specifications cover the entire range for each bath, not just the best temperature.

  All Micro-Baths have RS-232 ports and can be used with MET/TEMP II software (described on page 81). Also included are contacts to calibrate a thermal switch, eight set-point memory storage, ramp-rate adjust, and over-temperature safety cutout.

  You may have noticed we haven’t touted our CFC-free refrigeration. Yes, cold Micro-Baths are CFC-free, and also compressor-free. That’s right—no heavy, noisy compressor to lug around. We achieve our temperature range and stability with only one moving part. This means more durability and less weight. Fluke Calibration manufactures and sells temperature calibration baths of every size and shape, and now we have the smallest and lightest baths in the industry to go with the dozens of other models we make.

  Look at the specs, price, and value of these portable instruments and you’ll know why Fluke Calibration is the number-one company in this business.
