Bottle Pressure Tester
(Ref. S-401)

For Plastic Bottles and other containers.      






The illustration shows a pressure tester designed for up to 3 litre PET plastic bottles which can be tested to a pressure of up to 14 bar. The tester uses compressed air or nitrogen gas to pressurise the sample bottle which is filled with water via the reservoir mounted on top of the test chamber.

The compressed air, or nitrogen, is fed to the top of the reservoir and controlled by a main operating valve and a snubber valve which regulates the flow of gas into the reservoir.

The sample bottle is secured by its neck in the closed test chamber and may be observed during the test through a polycarbonate safety window.

The test pressure is read from a large dial pressure gauge and should the bottle burst during the test, a red following pointer on the gauge will remain at the bursting pressure. If the bottle reaches maximum test pressure without bursting then the the pressure in the system is relieved by a slide valve before removing the bottle. A drain pipe and sump is provided to run off surplus water.

The testers are of rugged construction and designed to ensure safety and convenience of operation. They are attractively finished to fit into a laboratory environment.
