The MS1000 is a portable, hand-held, battery-powered corrosion meter. This versatile instrument measures the instantaneous corrosion rate with the Linear Polarization Resistance (LPR) technique. It also measures the current flowing between electrodes in the short-circuited condition with a high precision zero resistance ammeter (ZRA). The MS1000 can analyze two-electrode linear polarization resistance or galvanic type probes. The principle use of this instrument is to measure corrosion rates under various conditions in the plant, field, or lab.
