To use most PH Sensors, an amplifier circuit is required. This PH Sensor amplifier board is designed to work with our PH Sensor to provide a simple 0-5V analog output – perfect for Arduino!

The board also provides a few additional features including a calibration trimmer (located closest to the BNC connector) and a triggerable digital output (adjustable using the trimmer located closest to the output pins). There is also an onboard thermistor for temperature compensation.
