4 Probe Concrete Resistivity: Geometric Accessory for Resipod Meter

4-Probe Concrete Resistivity Geometric Accessory for Resipod Meter

Concrete resistivity testing is a key method for assessing the durability and corrosion risk of reinforced concrete structures. The 4-Probe Concrete Resistivity Geometric Accessory for Resipod Meter is designed to provide accurate surface and bulk resistivity measurements, even on concrete with complex geometry.

This accessory is used with the Resipod Concrete Resistivity Meter and is suitable for both field inspections and laboratory testing. It is widely used by engineers, inspectors, and material testing professionals.

Accurate Concrete Resistivity Measurements

The Resipod Geometric Accessory uses the 4-probe Wenner array method, a widely accepted technique for measuring electrical resistivity of concrete. It connects directly to the Resipod meter and delivers stable, repeatable results across different concrete types.

The adjustable probe spacing, ranging from 40 mm to 70 mm, allows testing of concrete with varying aggregate sizes and compositions. This flexibility ensures reliable readings under different site and environmental conditions.

Key Features

• Compatible with Resipod concrete resistivity meters
• 4-probe Wenner array configuration
• Adjustable probe spacing (40–70 mm)
• Suitable for surface and bulk resistivity testing
• Lightweight and easy to use on site
• Designed for laboratory and field applications
• Supports non-destructive concrete testing

How the Geometric Accessory Works

The geometric accessory communicates with the meter through Resipod Link software, allowing smooth data entry and accurate recording. During testing:

• The outer probes apply electrical current
• The inner probes measure voltage without disturbing the circuit

This setup reduces contact resistance and eliminates errors caused by wire resistance. As a result, engineers obtain accurate resistivity values that support reliable concrete evaluation.

Importance of Electrical Resistivity in Concrete Evaluation

Electrical resistivity measures a material’s ability to resist the flow of electric current. In concrete, it is closely linked to:

• Corrosion risk of steel reinforcement
• Moisture content
• Chloride ion penetration
• Overall durability and service life

Lower resistivity values may indicate a higher risk of corrosion, while higher values generally suggest better durability. Resistivity testing is often used alongside corrosion testing equipment to assess the condition of reinforced concrete structures.

Non-Destructive Testing for Complex Structures

The 4-probe resistivity method is a non-destructive testing technique that does not damage the structure. It provides fast and repeatable results, making it suitable for regular inspections and long-term monitoring.

The Resipod Geometric Accessory is designed for use on structures with irregular shapes, such as bridges, buildings, and infrastructure elements. Its robust construction allows reliable performance in harsh site conditions.

This accessory is commonly used with other Non-Destructive Testing Equipment for comprehensive structural assessment.

Applications

The 4-probe concrete resistivity accessory is widely used in:

• Bridges and flyovers
• Commercial and residential buildings
• Marine and coastal structures
• Parking structures
• Research and material testing laboratories

It complements a wide range of Concrete Testing Equipment and Material Testing Equipment used for concrete durability evaluation.
