OVERVIEW

What it does and why it is built this way

The AN-110 pairs a digital pH or ORP sensor with a compact transmitter. Calibration data lives in the sensor, so a replacement can be pre-calibrated in the lab and swapped in seconds.

Diagnostics track glass impedance and response, predicting when a sensor needs cleaning or replacement.
