The WPH2007 glass pH sensor is frequently used in the downstream engineering of biotechnology as well as the mining and smelting, papermaking, paper pulp, textile, petrochemical, and semiconductor electronic industries.The reference electrode and the glass or metal electrode are united in one shaft because they are intended to function as combined electrodes. Depending on the kind, a temperature probe may also be integrated.

Industrial pH Monitoring: pH and pH Sensor Basics
The WPH2007 sensor has large sensitive areas and strong mechanical shock resistance, which can bewidely used in various chemical processes including microbialtechnology, pharmaceuticals, food and beverages, sugar manufacturing, chlor-alkali, mining and smelting, paper-making, paper pulp, textiles, petrochemical industry and semiconductor electronic industry as well as fields such as waste watertreatment
The principleof pH/ORPsensor measurement is electrochemical method and galvanic battery principle. The primary battery is a system whose function is to turn chemical energy into electrical energy. The voltage of this battery is called electromotive force (EMF) which ismade up of 2half-cells, of which one is called ameasuring cell whose potential is related to specific ionic activity;the otheris a reference half-cell, commonly known as a reference sensor, which is generally interlinked with the measuring solution and is connected to the measuring instrument. The potential difference produced by the galvanic interaction inside the sensor is transmitted to the pH controller, and the corresponding algorithm is transmitted to display the pH value.The pH sensor wire is not waterproof, so it shall be avoided to be contact with water as far as possible.

Application of pH Sensor
Industrial wastewater engineering. Process measurements, electroplating plants, paper industry, drinks industry. Wastewater containing oil. Suspensions, varnishes, media containing solid particles. Two-chamber system for when electrode poisons are present. Media containing fluorides (hydrofluoric acid) up to 1000 mg/l HF. Isolated power supply design, data stability, strong anti-interference ability
03
Uses of pH Sensor
Adopt a big area PTFE liquid junction with easy maintenance and an advanced solid dielectric from across the world. Long-range reference diffusion route significantly increases electrode life in challenging conditions. Because the electrode is constructed from high-quality low-noise wire, the signal output may be produced for up to 40 meters without interference. It also has excellent precision, quick reaction times, and strong repeatability.
pH Calibration
Enter the PH calibration screen, the first PH electrode intothe4.00PH standard solution, standing for a moment, to be stable after the show, press the ENT, then the PH electrode into the 6.86PH standard solution Set the PH electrode into the 9.18PH standard solution, put it aside for a moment, after the test is stable, press ENT, the display shows the success of the calibration, the whole process of PH calibration complete
