Quick Introduction - 7190A

The Fluke Calibration 7109A is a portable calibration bath with four times more calibration throughput and twice the accuracy of Micro-Baths and dry-block calibrators.

The Fluke Calibration 6109A and 7109A Portable Calibration Baths are liquid baths that let process industry professionals calibrate four times more sanitary sensors per batch in less time and with twice the accuracy of other portable baths in this class. Larger than micro baths, 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.

So, how much time can I save?

Calibrate 4 sensors in half the time:

To help you see the benefits compared to another calibration bath, we put the 7109A up the 7103 Micro Bath.

A typical 3-point calibration of 4 tri-clamp sanitary sensors takes over 4 hours (259.45 minutes) using a 7103 Micro-Bath. The same calibration using a 7109A Portable Calibration Bath takes about 2 hours (130.0 minutes).

That’s a time savings of more than 2 hours per 4-sensor batch!

This table presents the details.
