micro-erosion meter (MEM) A device for measuring the rate at which an exposed rock surface is lowered, perhaps by weathering. It consists of a gauge which records the extension of a probe. For measurement purposes the unit is placed on three studs, already set in the rock surface, and which provide a reference level. The extension of the probe is then a measure of erosion.
