STANDARD ER PROBE
ER probes measure the change in electrical resistance of a sacrificial element exposed to the process fluid relative to a reference element sealed within the probe body. If the element corrodes uniformly the change in resistance of the exposed element over a fixed time period is directly proportional to the average corrosion rate for that period. ER probes can be used in both conductive and non conductive liquids and vapors.
HIGH RESOLUTION PROBE
High resolution ER probe has all the advantages of standard ER probe and can be applied in all environments and provide fast signal response and reliable measurement.
