Dedicated to the specimen taking gas as the testing medium, a set of economy testers are developed as its pulse pressure is lower, pulse frequency is high and the swelling capacity is small. It is applicable to the endurance test of fittings for fuel hose, turbo charger and intercooler. Thanks to electric proportional control,both pressure waveform and test temperature are adjustable and controllable.

Technical Features:
As the gas circuit control valve adopted is of high temperature leaking-free coaxial valve, it allows high response frequency and long service life;
The utilization of waste heat is up to 80%;
