Product Description Electrical resistance monitoring is an effective method of indirect monitoring on device corrosion. Measuring element is placed in the pipeline like a length of electrical resistance wire. As the cross-sectional area of measuring element is reduced by the corrosion of its medium, resulting in increased electrical resistance, the thickness reduction and corrosion rate of the test sample can be calculated by measuring the variation of electrical resistance value. When the objective conditions, such as measuring element material, corrosion by its medium, etc., are basically identical with those of the measured equipment, the corrosion rate of the measuring element can represent approximately that of the equipment.
