Model ER0250

Atmospheric Probe

View PDF version

Model ER0250 is a probe used to monitor corrosion in atmospheric environments. The probe consists of an element which is mounted onto an epoxy board. One side of the element is exposed to the corrosive environment while the other side is covered, acting as a reference element. The ER0250 connects to a special cable that allows it to be used with electrical resistance probe instrumentation. Replacement elements may be ordered without a cable. The probe comes with a 3/16" hole for easy mounting.
