Profometer® Corrosion Meter uses half-cell electrical measurement technology for the detection and mapping of steel reinforcing corrosion in reinforced concrete. A cable is connected to the rebar grid, and electrical potential is measured through fluid-saturated copper/copper-sulfate electrode probes. Data is collected in the rugged touchscreen controller and processed for mapping and reporting with the included Profometer Link software. The extent of active corrosion activity is easily measured and documented, and corrosion hot spots are quickly isolated.

This advanced instrument features a 7in (178mm) 800x480 pixel color touchscreen display with an intuitive user interface, illustrative display, and assisted workflow. The dual-core processor and 8GB flash memory allow efficient post-processing of measured data and storage for later download to the user’s PC. Customizable screen graphics and a pre-defined, ASTM-compliant layout enable fast, on-site data interpretation. The measurement range is from -1000 to +1000mV with 1mV resolution. The sampling rate is 900Hz, and the impedance is 100MΩ. The Profometer Corrosion Meter can also be configured to use third-party silver/silver chloride electrodes.

The CT-170 Profometer is equipped with a touchscreen and interface box and also comes with a charger, 82ft (25m) cable with clamp, USB cable, software, carrying case, and strap. The unit requires a Rod or Wheel Corrosion Electrode, purchased separately, for operation. The Rod Corrosion Electrode is used for single readings or on a manually-defined grid pattern. Available Single-Wheel and Four-Wheel Electrodes improve data collection accuracy and maximize productivity for assessing large areas. Both wheeled electrodes include a 5.6ft (1.7m) telescopic handle, encoder, and required cables.

The Corrosion Meter is designed to be an all-in-one instrument and shares hardware and electronics with the Profometer® 6 series of Cover Meters. The CTA-92 Conversion Kit, complete with a universal probe, converts this unit to a CT-160 Profometer Cover Meter.

Note: Due to export regulations, this item cannot be shipped outside of the United States.
