Model ER3110

ER Corrosion Probe | Non-Metallic Body | Cylindrical Element

View data sheet (PDF)

Model ER3110 is an adjustable-length, electrical resistance (ER) probe used to monitor metal loss and corrosion rate under above-ground storage tanks. The non-metallic body eliminates the possibility of galvanic interaction that can occur with metallic insertion rods, and the optional ground lead allows the sensing element to be electrically coupled to the tank or CP rectifier.

Key Features:
Robust – Cylindrical element is ideally suited for monitoring corrosion under storage tanks.
Versatile – Can be used to monitor the native corrosion rate or the corrosion rate under cathodic protection.

Probe Body	Glass Epoxy	Temperature Rating (w/ Nylon compression fitting)	150° F / 65° C
Element Seal	Epoxy	Pressure Rating	100 PSI / 7 Bar
Fill Material	Epoxy	Mounting	3/4" NPT Pipe Plug
