Specially designed for analysis of contaminated water samples

The 1200-S sc sensor is based on a high quality combination pH electrode. The perforated diaphragm, in combination with a polymerized solid electrolyte, makes this electrode particularly insensitive to contamination and guarantees low maintenance. The sensor is especially suitable for dirty media.

The electrode is factory calibrated and very stable. Typically, calibration is only necessary after a few weeks or after changing the sensor electrode. To maintain the accuracy and reproducibility of measurements, the manufacturer recommends replacing the electrode after about one year from the beginning of use.

Whether it is domestic or industrial waste water, drinking water or industrial water - the high-quality, application-specific design guarantees high reliability of the redox sensors. The digital technology also allows these sensors to be combined with other SC sensors if required.

ORP measuring principle (Redox potential)

In a redox potential system, measurements are made using an instrument that consists of an ORP electrode and a reference electrode. The measured potential is called the redox potential and depends on the ratio between the activities of the two components of the redox system and the number of electrons transferred. In many cases, the pH of the solution also affects the potential.

The potential εB of the reference electrode has a great influence on the potential E of the measuring circuit. To correct this effect, the potential of the measuring electrode can be referred to the hydrogen electrode. If εB is the potential of the reference electrode used, then the calculation is performed according to the following formula:

ε (H) = E + εB
ε (H) = cell EMF value
εB = half-cell potential

Such potentials provide a certain amount of information about the oxidation or reduction potential of the system. An increase in positive values indicates an increase in oxidation energy. The greater the negative potential, the higher the recovery energy. The area of practical interest is from +1500 to –1000 mV.

Standard potentials of the redox system can be determined for aOx = aRed (a = activity) and for pH = 0. This, in turn, corresponds to the standardized activity of hydrogen ions aH + = 1 mol per liter.

The stability and the ability to reverse the Redox system have a significant effect on the reproducibility of the measured redox potential.
