The MS3502E / MS3504E is a battery-
powered, intrinsically safe, remote data-
logger capable of measuring and storing data from all types of electrical resistance (ER) corrosion probes. The instrument is microprocessor-based and features a simple, menu-driven interface. The MS3502E / MS3504E has two / four probe connectors
to allow it to take measurements at two / four different locations.
Corrosion rate measurements are made
using a high-resolution electrical resistance method, measuring up to 65,535 probe units. 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 MS3502E / MS3504E 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 main battery power. The instrument’s memory is capable of storing more than 100,000 readings, and is stored in non-volatile Flash memory.
Stored data can be uploaded to any PC as a comma-delimited ASCII text file. Because the data is in ASCII text format, it can be imported into any standard data analysis program such as Microsoft Excel. Data can also be reviewed on the instrument’s LCD display for quick reference.
Stored data can be downloaded directly to a certified USB storage device. This eliminates the need
to remove the MS3502E / MS3504E from its site, or to bring a laptop PC to the site. This can be
particularly useful when collecting data from multiple MS3502E / MS3504E Data Loggers. And since the MS3502E / MS3504E is intrinsically safe, data can be downloaded from the unit even in hazardous locations.
The instrument is housed in a stainless steel NEMA 4X / IP 66 enclosure, and all external connections are weather-proof. This makes the MS3502E / MS3504E suitable for use in almost any indoor or
outdoor environment. |
