Ground support equipment can benefit from QED pressure gauges due to the rugged nature and long life. With just a single moving part, QED pressure gauges frequently outlive the equipment into which they are installed.

Emergency slides and rafts require a reliable, leak free pressure source. Assuring that there is sufficient energy in the supply system, QED pressure gauges are a vital component in providing this information to the operators of transport aircraft worldwide.

Fire extinguishers are but one of many stored energy devices which benefit from QED pressure gauges, pressure switches or combination pressure gauges with pressure switches in a single package. Checking a QED instrument to see that there is sufficient energy in the system prior to flight insures that fires will be extinguished, doors will open, slides will deploy, emergency braking will work and much, much more.

High pressure pneumatics are frequently used to open aircraft doors in the event of a failure of the primary system. Assuring that there is sufficient energy to perform this task is the job of the QED pressure gauge.
Properly pressurized missile guidance systems are essential for the correct function of the seeker in many weapons applications. Light weight, rugged, reliable QED pressure gauges provide a method for assuring the user that once launched, the missile will find its target.

All pressure gauges are calibrated and tested:
100% helium leak tested
100% calibrated against the master NIST traceable standards
Our goal is to deliver the best gauge solution to every customer, every time. Whether its a new application that involves R & D brainstorming or calibration for an instrument, its likely that QED has already built a gauge that meets or exceeds your requirements.

QED is the remaining manufacturer of mechanical cockpit accelerometers designed and tested to meet the demanding requirements of Mil-A-5885, Mil-A25719, Mil-A-27261 and other Mil-A specifications for:
Military
General Aviation
Agricultural
Aerobatic
These applications appreciate the quality and steady function of these instruments. Since the 1950s QED has been the manufacturer-of-choice for the Cockpit Accelerometer; the G-force instrument preferred by the pilots of trainers and transport aircraft worldwide. In the original, mechanical version, the QED cockpit accelerometer continues to keep QED as the first choice for pilots of trainer and transport aircraft and for military forces in 28 countries.

The correct pre-charge of the struts on manned and un-manned aircraft provide for longer life and best function. QED pressure gauges offer long life and accurate readings for this and other applications.
