Resistivity Meter

Model 2180

Magnetic Instrumentation Inc.

Model 2180 - Magnetic Instrumentation Inc.

The unit is compact and lightweight. The basic system is 7″ wide by 2.5″ high and 12″ long. When measurements are needed below approximately 100 micro-ohm-centimeters, the basic system is piggybacked onto a second enclosure that houses a power amplifier with a current gain of ten. The combined unit measures 7″ wide by 5″ high and 12″ long. The combined unit weighs 11.5 pounds. Two short cables interconnect the two enclosures for powering the power amplifier and routing the signals to the fixture or four point probe. The front panel of the basic system includes a 32-character backlit LCD display and a set of function keys. An easy-to-use menu will allow access to user defined parameters such as sample thickness, sample volume, and calibration constants; upper and lower alarm limits, relative measurements, and several others.

Corrosion Analysis

Resipod

PASI srl

Resipod - PASI srl

Resipod is a fully integrated 4-point Wenner probe, designed to measure the electrical resistivity of concrete in a completely non-destructive test. It is the most accurate instrument available, extremely fast and stable and packaged in a robust, waterproof housing designed to operate in a demanding site environment. The Resipod is the successor of the classic CNS Farnell Resistivity Meter.Surface resistivity measurement provides extremely useful information about the state of a concrete structure. Not only has it been proven to be directly linked to the likelihood of corrosion and the corrosion rate, recent studies have shown that there is a direct correlation between resistivity and chloride diffusion rate and even to determination of early compressive strength. This makes it one of the most versatile NDT methods for concrete.

PANELMAP

Boin GmbH

PANELMAP is a software package used to collect, edit, analyze and visualize measured physical parameters on rectangular semiconductor panels. PANELMAP can import data files from various metrology tools such as ellipsometers, thickness gauges and four point probes. The imported data can then be visualized or printed as line scans, contour plots, 2D or 3D plots or as a histogram.
