ORP Electrode, Gel-filled
Our gel-filled ORP electrodes are easy to use and maintain. They are able to adapt to various sample conditions.
Gel-filling technology has been improved to achieve 2 years life expectancy.(1)
Stability has been enhanced with the adoption of a special two-layer structure for the
liquid junction and water insoluble polymer gel. It minimizes the influences caused by flow-rate
during measurement, and is able to support samples with conductivity as low as 10µS/cm.
(1) Life expenctancy varies depending on factors sush as sample type, frequency of use and maintenance
