This is Electrode Probe for Liquid pH Value Detection Sensor Module. 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, we have Liquid pH Value Detection Sensor. This probe can be used with this pH sensor module. The electrode is made of a pH glass electrode and a reference electrode combined composite electrode, which is pH meter measuring sensor for measuring the concentration of an aqueous solution of H (pH value), it is widely used in various fields to be detected in the pH. The PH electrode has a single cylinder that allows direct connection to the input terminal of a PH meter, controller, or any PH device which has a BNC input terminal. The PH electrode probe is accurate and reliable that can give almost instantaneous readings. Features : BNC Connector is suitable for most PH meter and controller. Suitable for a wide range of application: Aquariums, Hydroponics, Laboratory, etc. Package Includes : 1 x Electrode Probe for Liquid pH Value Detection Sensor Module SKU: PGI-00328377 Category: Sensors
