CDV FS AVVI vacuum chambers have a touch-screen setup system where test cycles can be programmed instantly. The operator places products inside the chamber starts the cycle and can be focused on observing the samples during the test cycle.
Vacuum is generated by a Venturi system integrated in the chamber fed by a compressed air supply. If this energy source is not available, another version of this model includes an electric vacuum pump.
The vacuum creates a difference in pressure between the inside and outside of the specimen or sample. During an immersion test, bubbles are visible emanating from a leak, while doing a dry test, a liquid spill or drops will be visible in a case of a leak.
CDV FS AVVI vacuum chambers include a touchscreen that automatically controls desired vacuum level during a test and also testing time. Access is protected with personal passwords for each user (up to 15 users). It has two testing modes:
Quick Test: As its name describes it, a quick test where the user sets vacuum level and time and starts the test on the spot.
Programmable Recipes: Up 16 recipes can be set. Each recipe can be set with a personalized name, vacuum level and testing time. The user needs only to click on the name of the product and the chamber will start the programmed test cycle.
