7109A Calibration Time Savings Estimate

Calibrate 4 sensors in half the time

Compare the 7109A Portable Calibration Bath with a 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!
