    The pH electrod installation methods:
    PH electrod installation methods
    1. Side wall installation (*The pH electrode must be at an angle of 15 degrees to the liquid surface. Otherwise, it will affect the normal use of the pH electrode.)
    2. Flange mounted at the top
    3. Pipe installation
    4. Top installation
    5. Submersible installation
    6. Flow-through installation

    Tips: PTFE electrode dosing system

    1. The electrode should be installed in the bypass beside the main pipe, and a valve should be installed at its front end to control the flow velocity. The flow shall be as small as possible, generally, as long as the outlet has a stable aqueous solution drops. Electrodes should be installed vertically and go deep into active water, and the water outlet should be higher than the water inlet to ensure that the electrode is completely immersed in the solution.
    2. The electrode should be calibrated before installation.
    3. As the measurement signal is a weak electrical signal, its acquisition cable should be independent and avoided to be connected in a same cable connector or terminal with the power line and control line, so as to avoid interference or breakdown of measuring units.
    4. When measuring cables need to be lengthened, please choose to customize the length or contact customer service (more than 15m).

    PTFE pH electrode can be used in harsh environments
    This PTFE electrode is perfect for sewage treatment. Using it in a harsh environment such as strong acid and strong alkali. The measurement result is stable, fast and accurate. It is a very good PTFE pH electrode.

    Good PH probe at low price!
    The PTFE electrodes worked beautifully and the price was right! These things are so fragile and I was so worried it would be expensive to replace. Fortunately, they are inexpensive and available. Recommend this seller!

    I have been using the ATO pH electrodes
    I put the pH electrode in the pool and so far, so good. It has been in use for about 2.5 months and it is still working well, exceeding my life expectancy. I have been buying ATO electrodes for the past year.

    Good and cheap for me
    So far so good. I have had this pH electrode for about 1.5 months and it is still working good, which exceeded my expected life expectancy for it. Highly recommended!!!

    Lasted so long
    Not sure why this pH electrode has lasted so long. My pH device says its still fully functional after 6 months of ten-uses a day. Still holds less than 1% error slope.

    Digital pH/ORP Meter for Water Testing

    Digital pH/ORP meter is a cheap online pH/ORP controller. The pH/ORP meter can be used in various severe environment. It is used to test and monitor the pH (0~14) / ORP (-1000~1000mV) / temperature (0~100℃/32~212℉) of sewage, corrosive solution, liquid medicine, beer, drinking water, food, etc. The pH controller transmits standard output signal 4-20mA to digital panel meter/VFD/PLC/recorder, or RS485 signal to a computer for remote monitoring and recording.
