Test posts follow the test task
Test-post directions include potential, current, sacrificial-anode, insulating-joint, casing, crossing and continuity functions. Start with the measurement task, circuit count, wiring and installation point.
Reference electrodes follow the medium and use
Reference-electrode directions include long-life and portable copper sulfate, together with silver/silver-chloride directions for seawater or chloride environments. Fixed, portable and control uses need different interfaces.
Treat the monitoring chain as a whole
Reference electrodes, test posts, acquisition equipment and a potentiostat may form a measurement or control chain. Include the system drawing or wiring requirement when requesting a review.
Key points
- Test posts organize test and wiring points
- Reference electrodes provide a measurement basis
- Function, medium and installation must align
