The WPH1105 pH sensor, which is used to test PH, is also known as a primary cell. A mechanism called the primary battery transforms chemical energy into electrical energy. Electromotive force (EMF) is the term used to describe this battery’s voltage. Two half-cells make up the electromotive force (EMF) in question.
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

(Modbus RTU protocol)
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 other is 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. WKP100 is a digital sensor with RS485 designed by our company for the aquiculture industry, which can be used to measure the change of pH/ORP value in an aqueous solution system within the range. The sensor with a standard RS485 MODBUS-RTU protocol interface, which can be connected with the host computer conducts remote communication Each sensor is manufactured with our patented Axial Ion Path® reference technology, proprietary Low-Noise & High Temp Signal Cable along with proprietary ruggedized, high temp and coat resistant glass formulations.
