Cirrus SR20: Salt Meters | Salinity Testers

Salt meters use electrochemical sensors to detect the presence and concentration of salt ions. By assessing salt levels accurately, they provide data to ensure aircraft surfaces are maintained within safe, noncorrosive conditions.

Salt, especially in coastal or humid environments, can accelerate the corrosion of metal components. Regular salt measurement helps prevent this, ensuring safety and reducing repair costs over time.

Salt meters are commonly used on aircraft fuselage surfaces, landing gear, and other metal parts exposed to harsh environmental conditions. This helps maintain structural integrity and extend component lifespan.

Salt measurements should be conducted based on environmental exposure and risk factors. For aircraft operating in coastal or humid regions, where salt levels are typically higher, measurements may be needed weekly or even after specific flights. For those in less corrosive environments, monthly checks are often sufficient. Regular monitoring of salt levels helps prevent corrosion on critical components, supporting safety and reducing maintenance costs.

Salt readings inform cleaning schedules and protective coating applications. By knowing salt concentrations, maintenance teams can prioritize anti-corrosion treatments on vulnerable parts of the aircraft.
