I. Introduction

A. General Description

The MS4500E-HC is a hand-held, battery powered, corrosion meter capable of measuring and storing data

from all types of electrical resistance (ER) corrosion probes. The instrument is light weight,

microprocessor-based, and features a simple, menu-driven interface using a keypad and a backlit

graphical LCD display.

Corrosion rate measurements are made using the electrical resistance method. Essentially, the instrument

measures the resistance of the probe element which changes over time, as metal loss occurs. The rate of

change is directly proportional to corrosion rate. This method finds a wide variety of applications since it

can be used in conductive and nonconductive environments such as petroleum, chemical, water, soil, or

even atmosphere. The new high-resolution measurement of the MS4500E-HC detects smaller increments

of metal loss, providing faster response than traditional ER instruments.

After taking a reading, the instrument displays metal loss in mils and corrosion rate in mils per year (mpy).

The reading can then be stored to memory or discarded. All stored readings are automatically time and

date stamped. Readings are stored to non-volatile Flash memory which retains data without the need for

a battery backup.

The MS4500E-HC High Resolution ER Data Logger can store 16,000 readings per probe on up to 250

different probes (4 million total). Stored data can be downloaded directly to a USB Flash (“jump”) drive in

non-hazardous areas. Data can be opened and charted using the provided CDMS software, or can be

imported into any standard data analysis (spreadsheet) program such as Microsoft Excel. Data can also be

reviewed and charted on the instrument’s LCD display for quick reference.

B. Principles of Operation

The MS4500E-HC High Resolution ER Data Logger operates on the Electrical Resistance (ER) technique

and is used in conjunction with an ER probe. The ER probe utilizes a resistive sensing element

manufactured from the material of interest (or a close approximation) which is exposed to a corroding

environment. This is called the Exposed or Corroding Element. The resistance of the Exposed Element

is directly related to its thickness, so as the element corrodes the resulting loss of metal causes a

proportional

increase in

the element’s resistance. The probe also contains an internal Reference

Element which is used to compensate for the influences of temperature on the Exposed Element.

The MS4500E-HC High Resolution ER Data Logger is designed to work with any standard ER probe,

but it is recommended that Cylindrical and Large Flush type probes be used to ensure optimum

performance. Their physical design places the Reference Element in closer proximity to the Exposed

Element compared to other probe types, providing more effective temperature compensation and

thus reducing the effects of thermal noise.

Because they are designed to corrode, ER probes are sacrificial in nature. Each ER probe will have a

finite life that is based on the element thickness. ER probes are available in a number of geometries

and thicknesses designed to suit a wide variety of applications. Table 1 lists the common ER element

options available from Metal Samples and the effective life of each.

Table 1. Standard ER Probe Elements

The MS4500E-HC High Resolution ER Data Logger measures an ER probe utilizing a high-resolution, 16-

bit measurement. This allows the unit to detect much smaller amounts of metal loss, thus

responding faster to corrosion events and upsets. At 16-bit resolution the MS4500E-HC ER Data

Logger can measure metal loss amounts as small as 0.004% of the probe life. For highly sensitive

probes such as the 5-mil large flush shown above, that results in a detection limit of less than one

angstrom.
