PH Controller 2 Point Calibration 2 Relay Out

The setting of Alarm Levels: PH Controller 2 Point Calibration 2 Relay Out, Digital pH Controller, pH Controller Auto Dosing
Lower Level Dosing Pump / Alarm Setting: Press REED button lower side rotate screw provided on the right side to set lower-level alarm/relay output if pH Value of solution goes down to this value relay 1 will turn ON and provide its potential-free contact as output.
Higher Level Dosing Pump / Alarm Setting: Press REED button upper side rotate screw provided on the right side to set Higher level alarm/relay output if pH Value of solution goes higher to this value relay 2 will turn ON and provide its potential-free contact as output.

Construction of pH meter:
The pH sensor or probe of modern pH meter a combined type. Which test and reference electrodes are placed into a Glass tube-like structure. The combined electrode consists of the following parts-

design and Construction of pH meter Probe

1. Glass bulb: It a sensor that senses the H+ ion concentration and it made from special type of glass and membrane. The glass bulb consists of 0.1 M HCL Solution.
2. Internal electrode: this electrode made by silver chloride.
3. Internal solution: The silver chloride electrode dipped in buffer solution of 0.1 M KCL of pH 4 to pH 7.
4. Reference Electrode: It is also the silver chloride electrode use for reference.

5.Junction: It is made from ceramic junction also called as diaphragm that allows the contact of sample solution and reference electrolyte. It should not disturb the electric connection between both electrodes.
6. Filling hole: It is used for refilling the electrolyte if required.
7. Electrode body: the body is from non-conductive glass or plastic material and may coated by epoxy to prevent glass bulb.
when acidic solution is rich in H+ ion concentration. When pH probe dipped in an acidic solution, the H+ ion moves close to the glass membrane of the sensitive glass bulb (external side of the bulb). Hence Similar reaction occurs inside the bulb, which filled with buffer solution of neutral 7 pH. This neutral buffer solution has constant number of Hydrogen ions. The H+ ions present inside the bulb also moves close to glass membrane (internal side of the bulb). Hence, this causes the difference in the concentration of hydrogen ion or degree of hydrogen ion activity across the membrane causing difference in the potential (voltage). When the hydrogen ion concentration inside the glass bulb is less than the outside solution (test solution), then the given solution is acidic and hence the pH is lower than 7.

When the Hydrogen ions concentration across the membrane similar then it called as neutral pH and the pH equal to 7. while If the concentration of hydrogen ion of inside the bulb than outside solution then the given solution is alkaline and the pH is more than 7. Hence pH meter measure the potential difference at both the electrodes and calculate the pH as per the Nernst equation.
