Digital Air Data Testers for General Aviation

 

In January I bought a PS-525 Pitot/Static tester from you. 

This is just to let you know how pleased I am with it.
I have used it maybe twice a week since purchase, on a wide variety of general aviation aircraft up to and including the Pilatus PC-12.

I much prefer it to the traditional Pitot/Static testers which are both bulky, noisy and slower to respond. I also like the fact that differential pressures across the Airspeed sensor don´t cause damage to it as with a conventional tester with an ASI.

Occasionally I rent an RVSM Air Data Testset which has a very tight tolerance. I have connect the PS-525 to it and used it as
a calibration standard. Again I can testify that the PS-525 is extremely simple to calibrate and appears not to loose accuracy.

Many thanks,
