Product Description

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 temperature 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 calibration 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.
