Extremely simple to calibrate…
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.

We just received our new PS-525 pitot-static test box and are delighted to have it and begin to put it to use. I am thoroughly impressed at the accuracy of both the altimeter and the airspeed indicator – simply amazing!
