Model MS1500L - Handheld LPT Corrosion Data Logger

Corrosion meter capable of measuring and storing data from all types of 2- or 3-electrode linear polarisation resistance (LPR) corrosion probes

The MS1500L is a hand-held, battery-powered, intrinsically safe corrosion meter capable of measuring and storing data from all types of 2- or 3-electrode linear polarisation resistance (LPR) corrosion probes. The instrument is light weight, microprocessor-based, and features a simple, menu-driven interface using a 12-key keypad and a 4-line LCD display.

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

The MS1500L incorporates a high-precision zero-resistance ammeter (ZRA) for measuring galvanic current between electrodes. It also offers a high-precision voltmeter for measuring the open-circuit potential between electrodes.
