The Alt-621 indicators are designed specifically for replacing the analog indicators in pitot-static testers. The sensors are technician-proof, not sensitive to sudden pressure changes, which contributes to reduced annual maintenance costs.
The indicators are powered by an external 12 volt DC power adapter (included).
