Mensor manufactures a wide variety of pressure measurement and calibration products including the two specific avionics instruments below. The CPA2501 Avionics digital pressure gauge is used in aviation and aerospace applications for calibration of altimeters and airspeed indicators, displaying altitude, airspeed, altitude rate (vertical airspeed) and airspeed rate (acceleration). The CPA8001 Air data test set (ADTS) is a pressure controller specially designed for the calibration of measuring instruments involved in aerospace technology. The CPA8001 controller can be used for calibration of both analogue altimeters, rate of climb indicators and speedometers and digital sensors or air data computers.
