The PS-425 Pitot-Static tester is a low-maintenance, digital tester that is fully portable. The PS-425 is powered by an internal rechargeable 12 volt battery (included in purchase), which enables the test set to be used completely independent of any external power source. A connector is provided for an external 12 volt DC power adapter (included). The PS-425 incorporates the altitude, VSI, and airspeed in one single display. The PS-425 is designed and priced for non-RVSM markets, and includes two quick-connect hoses, 12 VDC power adapter, calibration certificate, and a limited 2-year warranty. This product is ideal for performing simple go/no-go leak tests, as well as for general use as a low-end pitot-static tester. It only requires an annual calibration, and the sensors are technician-proof, which contributes to reduced annual maintenance costs.
Altitude goes up to 35,000 feet and is displayed in 2 and 5-feet increments and includes a VSI – Vertical Speed Indicator
Displays airspeed in Knots, in increments of 1 Knot, up to 500 Knots max.
