MS1000 LPR Corrosion Meter

View PDF version
User's Manual in PDF

The MS1000 is a hand-held, battery-powered corrosion meter. This versatile instrument measures the instantaneous corrosion rate and electrochemical current between the electrodes of any standard 2-electrode linear polarization resistance (LPR) probe.

Corrosion rate measurements are made using the linear polarization resistance technique. The instrument measures the current required to polarize the electrodes of a probe to a known potential. From the polarization potential and the measured current, polarization resistance can be calculated. Then, using Faraday’s law, instantaneous corrosion rate is calculated from polarization resistance.

The MS1000 is designed to calculate the corrosion rate in mils per year (mpy) for carbon steel. Multiplication factors for several common alloys have been included on the front panel of the instrument for quick reference. Multiplication factors for other alloys can be easily calculated using the formulas supplied in the operation manual.

The MS1000 also offers a high precision zero resistance ammeter (ZRA) for measuring the electrochemical current between electrodes. This function may be used to measure the galvanic current between electrodes of dissimilar alloys.

The MS1000 has a simple function key interface, using a 4-key keypad and a 4-line LCD display. The instrument also offers low-battery detection and an auto-shutoff feature to conserve battery life.
