Features:1. The electrode is composed of a PH glass electrode and a silver chloride silver reference electrode, and is a measuring component of the PH meter for measuring the pH value of the aqueous solution.2. The electrode plug should be kept clean and dry.3. The external reference solution of the electrode is 3NKCL solution.4. Avoid cross-contamination between solutions during measurement to avoid affecting measurement accuracy.5. The electrode should avoid long-term immersion in acidic fluoride solution.Specification:Module Power : 5.00VModule Size : 43 * 32mmMeasuring Range :0 - 14PHMeasuring Temperature: 0 - 80 CAccuracy : 0.1pH (25 C)Response Time : 1minpH Sensor with BNC ConnectorpH2.0 Interface ( 3 foot patch )Gain Adjustment PotentiometerPower Indicator LEDPackage List:1 * PH Sensor Module1 * PH Probe.
