DescriptionNeed 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. It has an LED which works as the Power Indicator, a BNC connector and PH2.0 sensor interface. To use it, just connect the pH sensor with BNC 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 compact plastic box with foams for better mobile storage. Attention:In order to ensure the accuracy of the pH probe, you need to use the standard solution to calibrate it regularly.Generally, the period is about half a year. If you meaure the dirty aqueous solution, you need to increase the frequency of calibration.DIAGRAMAPPLICATIONWater quality testingAquacultureSPECIFICATIONModule Power : 5.00VModule Size : 43mm×32mmMeasuring Range:0-14PHMeasuring Temperature :0-60 ℃Accuracy : ± 0.1pH (25 ℃)Response Time : ≤ 1minpH Sensor with BNC ConnectorPH2.0 Interface ( 3 foot patch )Gain Adjustment PotentiometerPower Indicator LEDCable Length from sensor to BNC connector:660mmBOARD OVERVIEWpH Electrode SizepH Electrode CharacteristicsThe output of pH electrode is Millivolts,and the pH value of the relationship is shown as follows (25 ℃):DOCUMENTWiki (PH meter)pH and EC Probe Holder 3D Model (by Rayuela)SchematicPCB layoutPH composite electrode manualArduino sample code / ph sensor arduinoZips for all aboveSHIPPING LIST1 x Gravity: Analog pH Sensor / Meter Kit For Arduino1 x pH probe (BNC connector)1 x pH sensor circuit board1 x Analog cable
