    Brief introduction:
    Redox potential (Eh) as the media ( including soil , natural water , media , etc. ) of a comprehensive indicator of environmental conditions , has been used for a long time, it is characterized by the media relative degree of oxidation or reduction . For a long time the redox potential is the use of a platinum electrode direct assay. Upcoming platinum electrode and a reference electrode directly into the medium was measured . However, when measuring weak balance system , due to the inert platinum electrode is not absolute , the surface oxide film may be formed or adsorb other substances . Influence of the redox couple on a platinum electrode electronic exchange rate , thus establishing equilibrium potential is extremely slow , and in some medium, subject to a few hours or even a day or two , and the measurement error is very large, usually 40-100mV. If the full account of the dynamics of the surface properties of the platinum electrode and the electrode potential established , complex medium , if determined by the redox potential depolarization method , more accurate results can be obtained in a short time of 2 minutes , usually less than 10mV or better.
     Main features:
    1 , measurement item ORP, pH and temperature measurement , can be measured one by one , three parameters can be measured simultaneously ( when used in combination with the PC ) .
    2 , MCU and PC compatible ( can also be used in the field independently associated with PC use )
    3, through the USB port and PC combined.
    4 can be used with a PC or laptop in conjunction with, the entire process is done automatically measurement and data processing under program control , in addition it can automatically draw the curve and the results are automatically saved, it can be selected based on a single measurement or data acquisition cycle .
    5. Determination of the conventional measurement methods, the use of positive and negative measured depolarization method.

    6 , better fidelity . Measurement result is the end result , rather than the traditional method of periodic results .
    7 , to shorten the measurement time .
    8 , measurement and data processing all automatically.
    9 , the reference electrode potential look-up table is automatically determined by the temperature
    10 , higher instrument integration, smaller, more feature-full . 

    Technical parameters:
    1, measuring range: 0 to + -1999.9mV; minimum reading for 0.1mV
    2, ORP measurement accuracy: less than 10mV
    3, the input impedance: > 10 th European 10
    4 , to complete a measure of the minimum time : 2 minutes
    5. Power 8.4V lithium battery
