User's Manual (PDF) |
The MS6200L is a bench-top data logger
capable of measuring and storing data from
all types of linear polarization resistance
(LPR) corrosion probes. The instrument is
microprocessor-based and features a simple, menu-driven interface using a 2-key keypad and a 2-line LCD display. It is housed in a
rugged but lightweight plastic enclosure and is ideally suited for use in laboratory environments. The adjustable handle can be used for carrying the unit, or can be used as a tilt stand to adjust the viewing angle.

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, the instantaneous corrosion rate can be calculated from polarization resistance.
The MS6200L 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.
The MS6200L takes probe readings on a user-programmable logging interval. Readings
are time and date stamped as they are taken, then stored to memory. Between readings, the
instrument remains in a “sleep” mode to conserve energy. The instrument’s memory is capable of storing 3,000 readings, and is protected by a lithium back-up battery. Stored readings can
be downloaded to a computer via USB or serial port for further analysis using the provided software. The software provides a simple and intuitive interface for downloading, viewing, and graphing the data. |
