Description
Vacuum tester model VT 350D (digital) is an instrument for testing packaging under controlled vacuum conditions. It features a round container with a cylinder of Plexiglas and a lid of white PVC, ensuring good visibility of the specimen during the test. A Jumo program controller regulates vacuum from 0–500 mbar and shows the values on a digital display. A predefined vacuum ramp is included and can be adapted by the user to suit specific test requirements. The unit operates from a 230 V 50/60 Hz mains supply. This digital vacuum tester from manufacturer Aerne Analytic is intended for laboratory and quality-control use where packaging seal performance must be assessed under reduced pressure. The transparent Plexiglas construction allows continuous observation, while the programmable controller with digital readout supports consistent, repeatable vacuum ramps. The round-container format and straightforward electrical connection make the VT 350D a practical choice for routine packaging integrity evaluation without additional complex peripherals beyond a standard laboratory power outlet.

Questions about Vacuum Tester to test packing VT 350D
What is this article?
Vacuum Tester to test packing VT 350D is the article on this page. Luminix Health distributes Aerne Analytic for laboratory use. It sits in pH meters, inside pH & electrochemistry, in Lab instruments.
A pH meter reads the electrode and displays pH, after calibration with at least two buffers. A meter that cannot be calibrated is a voltmeter. Resolution to 0.001 is not the same as accuracy. Portable and benchtop meters differ in the electrodes they accept and in the data they store.
A pH meter is a voltmeter on a glass electrode. The voltage tracks hydrogen-ion activity, and the electrode is converted to pH only after it is adjusted with buffers of known value. Conductivity measures how well a solution carries a current, which for dilute salts tracks concentration. Dissolved oxygen and titration are further electrodes on the same idea: a sensor, a standard, and a reading that is only as fresh as the calibration. Buffer values and chemical identity sit on PubChem. Accreditation of the calibration laboratory is the field of BELAC and EURAMET.
