    Production Introduction
    The PH/ORP meter is a precision meter used to detect the pH/oxidation-reduction potential of liquids. It is designed with a microcomputer based on the principle of the primary battery and is simple to operate and easy to maintain. Not affected by color, turbidity, colloidal substances, oxidants and reducing agents, it is suitable for the determination of various media such as clean water, wastewater, industrial water, chemical reagents, etc., and is widely used in agriculture, environmental protection and industry.
     
     
     
    The sensor uses a composite electrode, which can eliminate the influence of the inconstant "K" value,
    A long-term, stable and accurate measurement of PH is realized. The internal structure of the sensor is shown on the right.

    Principle of Measurement
     
    PH meter is a potentiometric method to measure the PH of a solution, so the PH meter works in such a way that, in addition to measuring the PH of a solution, it can also measure the electromotive force of a battery.
    The PH is the activity of hydrogen ions in a substance, and the PH is the negative of the logarithm of the concentration of hydrogen ions.The main measuring components of PH meter are glass electrode and reference electrode. Glass electrode is sensitive to PH and reference electrode has stable potential.If you put these two electrodes of the PH meter together in the same solution, you make a galvanic cell, and the potential of this galvanic cell is the algebraic sum of the potential of the glass electrode and the reference electrode.
    The reference electrode potential of PH meter is stable, so in the case of temperature remains stable, the potential change of the galvanic cell composed of the solution and the electrode is only related to the potential of the glass electrode, and the potential of the glass electrode depends on the PH value of the solution to be measured, so through the measurement of the potential change, the PH value of the solution can be obtained.

    Q&A
     
    ORP (Oxidation - Reduction Potential)
    Oxidation-Reduction Potential (ORP) measures the oxidizing properties of any sanitizer (chlorine) present in the water. ... ORP is probably the most common method used by chemical controllers to measure sanitizer level, and the most inexpensive type of system.
     
    What causes ORP to rise?
    If there are lots of potent oxidizers around, and not so many reducers, ORP rises because the electrode senses more oxidizing "power" in solution. Likewise, ORP drops if it senses more reducing power in solution. ... Often, ORP goes down as pH rises. A typical aquarium ORP reading will change on the order of 59 mv/pH unit.
     
     
    What should be the ORP of drinking water?
    Since the movement of electrons is electricity, ORP is measured in millivolts. Drinking water should have a rating of least -50 millivolts, but it's not often the case. Filtered water can have ORP values ranging from 357 to -25, depending on the brand and type of water. It's most often measured using an ORP meter.
     
    Why is my ORP level low?
    A drop in the ORP indicates an increase in chlorine demand caused by reducing agents or contaminants entering the water. A decrease in ORP indicates that chemical reactions are about to occur. Compared to amperometric control, ORP is considered to be a more accurate measure of disinfection rate.2016年11月14日
     
     
    What does a negative ORP mean?
    A negative ORP reading indicates that a substance is a reducing agent. The lower the reading, the more anti-oxidizing it is. As such, a substance with an ORP reading of -400 mV is 4 times more anti-oxidizing than a substance with an ORP reading of -100 mV.
