Description：

This module helps engineers to read the high impedance mV signal of a pH/ORP electrode in a simple way. It provides ground isolation to eliminate noise interference. The input signal is sampled by a precision 16-bit analog to digital converter. Up to 6 modules can be linked to the I2C bus by setting a unique hardware-programmable address for each.
