ELECTRODES |
Contech offers wide range
of electro chemical sensors for the measurement of pH,
ORP, Conductivity, DO, different Ion Concentration and
Temperature . Choosing a right electrode for the
specific requirement is important and the following to
be considered while deciding an electrode for the
measurement : accuracy of measurement, electrode body,
reference construction and junction. Electrodes need to
be calibrated with standards for achieving proper
results. Electrodes should be stirred end maintained as
per instructions to enhance the performance and life. |
