DFRobot Gravity Analog pH Sensor Kit

Need to measure water quality and other parameters but haven't got any low-cost pH meter? Find it difficult to use with Arduino? DFRobot analog pH meter, specially designed for Arduino controllers and has a convenient and practical "Gravity" connector and a bunch of features. Instant connection to your probe your Arduino to get pH measurements at ± 0.1pH (25 ?). For most hobbyists, this great accuracy range and its low cost make this a great tool for biorobotics and other projects! It has an LED that works as the Power Indicator, a BNC connector, and a PH2.0 sensor interface. To use it, just connect the pH sensor with the BND connector, and plug the PH2.0 interface into the analog input port of any Arduino controller. If pre-programmed, you will get the pH value easily. Comes in a compact plastic box with foams for better mobile storage.
