Fluke 7109A-156 - Portable Calibration Baths, -25°C to 140°C, 115 VAC

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.

The 6109A-P and 7109A-P models come with a Process Input Module that measures various types of temperature sensors.

1. Current Fuse - Protects the Process Input Module and connected devices from accidental short circuit.
2. RTD Terminals - A test RTD connects to these terminals. The graphic on the panel shows the circuit diagram for a four-wire RTD.
3. Reference PRT connector - A reference probe plugs into this socket. Recommended Fluke Reference PRTs are models 5615-9-A and 5626-12-A. Other Fluke Reference PRTs with Type A INFO-CON termination are also compatible.
4. Thermocouple Input - A connector for a miniature thermocouple.
5. Transmitter Terminals - A 4-20 mA transmitter connects to the two transmitter terminals labelled mA LOOP and COM.
