Dfrobot SEN0169 Analog pH Sensor / Meter Kit for Arduino Development Boards

This is a DFRobot Gravity Industrial Grade Analog pH Sensor / Meter Pro Kit for Arduino.

Gravity: Analog pH Sensor / Meter Pro Kit For Arduino is a professional Arduino pH Sensor Meter Kit with an industrial electrode. The industrial ph sensor for Arduino has a built-in simple, convenient, practical connection and long life (up to 1 year), which makes it very suitable for long-term online monitoring. It has an LED that works as the Power Indicator, a BNC connector, and a PH2.0 sensor interface.

This industrial pH electrode is made of a sensitive glass membrane with low impedance. It can be used in a variety of PH measurements with fast response and excellent thermal stability. It has good reproducibility, is difficult to hydrolysis, and can eliminate basic alkali errors. In 0pH to 14pH range, the output voltage is linear. The reference system which consists of the Ag/AgCl gel electrolyte salt bridge has a stable half-cell potential and excellent anti-pollution performance. The ring PTFE membrane is not easy to be clogged, so the electrode is suitable for long-term online detection.
