(Scientific Grade Sensor and BNC connector not included) pH circuit designs that are available on the Internet today are antiquated and use a significant number of overly complex analog components. Atlas Scientific has reinvented and refined the pH Circuit of yesteryear.
Warning: It doesn't bring PH2.0 sensor interface! Only the probe! Need to measure water quality and other parameters but haven't got any low cost pH meter? Find it difficult to use with Arduino? Here comes an analog pH meter, specially designed for Arduino controllers and has built-in simple, convenient and practical connection and features.
