April 12, 2017 – Pharmaceutical and biotechnology manufacturers utilize many tri-clamp and sanitary sensors in their clean room production processes. These sensors require periodic calibration which halts production. The Fluke Calibration 6109A and 7109A Portable Calibration Baths are clean room compatible and are designed to calibrate these sanitary sensors.
The 6109A and 7109A feature tank volumes of 112 mm square tank opening by 154 mm deep, allowing technicians to immerse four sanitary sensors at a time — including batches of odd shaped sensors of varying lengths and diameters, which can be accommodated with room left for a reference thermometer. The display panel, keypads, decals, and feet of the 6109A and 7109A baths are made from synthetic materials that don’t harbor bacteria. Their stainless steel panels and tank are easy to clean, withstand harsh sterilizing chemicals, and are rust resistant — ideal for clean room use.
The baths feature:
- Temperature ranges that cover most clean process applications:
- 6109A: 35 °C to 250 °C.
- 7109A: –25 °C to 140 °C.
- Display accuracy of ±0.1 °C that provides 4:1 test uncertainty ratio (TUR) for critical applications.
- An adjustable probe fixture accessory that holds up to four tri-clamp sensors securely inside the tank during calibration.
- Fixed bail handle and two bottom recessed handles for transport up and down stairs and across catwalks.
- Traceable NVLAP accredited calibration included standard.
The baths have color displays that indicate bath fluid temperature, setpoint temperature, and heating/cooling status for ease of use. A ready indicator on the top of the baths changes color from amber to green providing a 360-degree visual indication when the bath is ready for measurement. When the bath is off, a hot warning indicator lets technicians know when the bath fluid is at a safe temperature for transport.
