Proceq Profometer Corrosion Meter

Proceq Profometer Corrosion Rate Meter

The Profometer Corrosion Meter uses half-cell electrical measurement technology to detect and map steel rebar corrosion in 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. Active corrosion area is easily measured and documented and corrosion hot-spots are quickly found.

This is the instrument for quick and easy corrosion rate measurements, with a 7in (178mm) 800x480 pixel color touchscreen display and an intuitive user interface, graphic display and guided workflow. Dual core processor and 8GB flash memory for efficient post processing of measured data and storage for later download to user’s PC. Customizable screen graphics and a pre-defined, ASTM compliant layout for fast on-site data interpretation. Measurement range is -1000 to +1000mV with 1mV resolution. Sampling rate is 900Hz and impedance is 100MΩ. Can also be configured to use third-party silver/silver chloride electrodes.

The Profometer Corrosion Meter includes the touchscreen and interface box, charger, 82ft (25M) cable with clamp, USB cable, software, carrying case and strap. Requires a Rod or Wheel Corrosion Electrode, sold separately. The Rod Corrosion Electrode is used for single readings or on a manually defined grid pattern. Single-Wheel and Four-Wheel Electrodes improve data collection accuracy and speed for large areas. Both wheeled electrodes have a 5.6ft (1.7M) telescopic handle, encoder and required cables.

Corrosion Measurement

Corrosion measurement is used in many industries including construction, manufacturing and marine to detect and prevent damage to metal components. Corrosion can cause economic losses, safety risks and environmental hazards. Accurate corrosion measurement helps to find potential problems, monitor corrosion protection systems and optimize maintenance schedules. This section introduces corrosion measurement principles, techniques and instruments used in different applications.

Features and Specifications

When choosing a corrosion measurement instrument consider:

• Measurement Range: The instrument’s ability to measure corrosion rates within a certain range, usually in millivolts (mV) or microamperes (μA). A wider range means the instrument can handle more corrosion.

• Resolution: The instrument’s ability to measure small changes in corrosion rates, usually in millivolts (mV) or microamperes (μA). High resolution is for precise measurement and accurate data.

• Accuracy: The instrument’s ability to measure corrosion rate accurately, usually as a percentage of true value. High accuracy is for reliable data to make maintenance and repair decisions.

• Data Storage and Analysis: The instrument’s ability to store and analyze data, including data logging, graphing and reporting. Good data storage and analysis means comprehensive monitoring and trending of corrosion over time.

• Software Compatibility: The instrument’s compatibility with software for data analysis, reporting and integration with other systems. Good software integration makes the instrument more user friendly and functional.

• Price: The instrument’s cost including any additional features, accessories or maintenance. Pricing helps to evaluate the overall value and long term investment in the instrument.

Applications and Industries

Corrosion measurement instruments are used in:

• Construction: To measure corrosion of reinforced steel in concrete structures such as bridges, buildings and roads. Integrity of these structures is critical for public safety and infrastructure life.

• Manufacturing: To measure corrosion of metal components in production process such as pipelines, tanks and machinery. Preventing corrosion in manufacturing environment helps to maintain operational efficiency and product quality.

• Marine: To measure corrosion of boat hulls, propellers and other metal components in seawater and freshwater environments. Corrosion measurement in marine environment is critical for vessel safety and performance.

• Water Systems: To measure corrosion of pipes, valves and other metal components in drinking water, wastewater and industrial water systems. Integrity of water systems is essential for public health and environmental protection.

• Oil and Gas: To measure corrosion of pipelines, tanks and other metal components in oil and gas production, transportation and storage. Accurate corrosion measurement in oil and gas industry prevents leaks, spills and other hazardous events.

Calibration and Maintenance

Calibration and maintenance is crucial to ensure the instrument is accurate and reliable. Calibration is the process of adjusting the instrument to a known standard while maintenance is the process of regular checks and repair to prevent instrument failure. Calibration and maintenance procedures may include:

• Check Instrument’s Electrical Potential: Regularly check and adjust the electrical potential to get accurate measurement.

• Verify Instrument’s Measurement Range and Resolution: Ensure the instrument can measure within its specified range and detect small changes in corrosion rates.

• Clean and Replace Electrodes and Sensors: Keep electrodes and sensors clean and replace as needed to maintain measurement accuracy.

• Update Software and Firmware: Regularly update the instrument’s software and firmware to get optimal performance and compatibility with other systems.

• Routine Check on Electrical and Mechanical Components: Regularly inspect and maintain the instrument’s components to prevent failure and extend its life.

Corrosion measurement is used in many industries and choosing the right instrument is critical to get accurate and reliable results. By considering the features and technical specifications, applications and industries, calibration and maintenance requirements and pricing, users can select the right corrosion measurement instrument for their needs. Calibration and maintenance is also crucial to ensure the instrument is accurate and reliable over time.
