The ACS Instrument 7400S is a laboratory leak test bench — sometimes referred to as a leak detector — designed specifically for integrity testing of flexible containers such as flexible packaging, pouches, and envelopes. Machines of this type are used in quality-control environments to detect and measure the presence of leaks in sealed flexible packaging, ensuring product integrity before goods reach the end consumer.
The instrument operates on a differential pressure principle. The flexible container under test is placed inside a sealed enclosure, where a vacuum is applied. This causes the container to inflate, at which point it is clamped between the two horizontal walls of the enclosure. The inflated container then exerts a force on an internal pressure sensor, and this force serves as a measure of the container's internal pressure. The leak test itself consists of monitoring any variation in the force registered by that sensor between the beginning and end of a defined measurement stage — a change in force indicating the presence of a leak.
Key performance parameters include a differential pressure measurement range of ±5,000 Pa and a pressure test range spanning from −55 hPa to +950 hPa, allowing the instrument to accommodate a broad range of packaging types and integrity specifications. The unit is driven by a motor rated at 0.75 kW, and it is described as both automatic and autonomous in operation.
User interaction is handled via a built-in touchscreen, which is used to control the instrument and configure test parameters. Results can be exported using a USB key. This 2019 unit is offered in used condition from a seller based in France, and documentation is available with the machine.
