CTA-97 Four-Wheel Corrosion Electrode is used together with the CT-170 Profometer® Corrosion Meter for efficient measurement of active corrosion in steel-reinforced concrete. A Wheel (four or single) or Rod Corrosion Electrode is required for testing with the CT-170 Corrosion Meter. The four-wheel electrode comes with a carrying case that contains 5.6ft (1.7m) telescopic rod, encoder, cables, spare parts, tool kit, and 250g each of copper sulphate and citric acid. This model performs faster than the rod or single-wheel models, and is recommended when measuring large horizontal surfaces.
- Copper/Copper Sulphate half-cell electrode
- Significantly faster measurements of larger areas
