Pen Type PH Electrode Sensor BNC Connector Probe Pool Water Factory Industry Experiment Laboratory pH Composite electrode E-201 The composite electrode and the E-201C E-201PH composite formed by the pHelectrode and a silver-silver chloride reference electrode, is a polycarbonate shellrepression, it is a pH meter measuring for key element for the measurement of an aqueous solution of hydrogen ions in the depth of the pH value, widely used in thechemical industry, the pharmaceutical industry and research career pH detection. Features: When the PH electrode used for the first or long home without, activated 2 hourselectrode ball soaked in 3.3N potassium chloride solution Sino-French Measurement should be washed in distilled water and wipe dry with filter paper to prevent impurities into the electrode bulb and liquid contact Ministry should also beimmersed in the test solution within E-201 pH composite electrode, not be added to the outside of the reference solution. The Cable about 0.8M Specifications: Product Name:E-201 Laboratory pH electrode Temperature:5-60 Celsius Zero potentiometer(pH):71 Internal resistanceM(25): 250 Theoretical percentage slope%:97% Terminal Blocks: BNC Plug Package include 1pcs E-201 pH electrode
