Leak Detectors

MultiCheck 2

By combining a headspace gas analyzer, leak detector and valve tester in one unit, the Dansensor® MultiCheck® 2 helps you achieve fast, consistent, and reliable quality control of your MAP packaging process.


Designed specifically for the coffee industry, the Dansensor MultiCheck 2 helps to ensure that the characteristic taste and aroma of your products are preserved and that your brand reputation is protected. It is equipped with specialized filters and sensors for coffee applications – though it is also suitable for other applications. In addition, you can conduct integrated valve leak and valve release tests on degassing valves with the optional valve testing unit (VTU), so the integrity of your entire package is accurately tested and recorded in a combined report.


Increase the uptime of your packaging line with this reliable analyzer and avoid time consuming troubleshooting exercises when inconsistencies arise. Moreover, reduce the risk of human error and improve your quality management with dependable data storage and real time data transfer. The instrument can store test results from more than 100,000 tests.


With the ability to conduct four tests in one – headspace gas analysis, leak detection, valve leak and valve release – the Dansensor MultiCheck 2 is 50% faster, takes less space, and is more user friendly than its predecessors. It takes up less space and is more user friendly with an intuitive user interface. In addition, there are dedicated ports for the test head and VTU and USB ports for connecting additional accessories, such as a barcode scanner or keyboard. It also includes the option to conduct a burst test, to help you establish the settings and limitations for your package testing. Up to 999 product test settings can be programmed into the unit to ensure consistent test parameters.


The Dansensor MultiCheck 2 is designed for easy maintenance and cleaning, so you can proactively preserve the accuracy of your measurements and ensure uptime. Use the self-rinsing backflush program regularly to remove particles and contaminants from the system and replace the easy-to-access filters on the test head.


Headspace gas analyzers & Leak detectors:

The Dansensor® MultiCheck® 2 combines the functions of both a headspace analyzer and a leak detector in one convenient unit. See other examples of single function instruments here:

  • Dansensor® CheckMate 3 
    A highly accurate benchtop headspace analyzer, the Dansensor CheckMate 3 is a cost-effective solution that allows for operators to measure both O2 and gas mixtures combining O2 and CO2.
  • Dansensor® Lippke® 5000
    Dansensor Lippke 5000 provides reliable seal strength and pressure leak testing of many types of packaging. It can be used in production, laboratory environments and throughout the supply chain to test package integrity.
  • Dansensor® LeakPointer® 3 and Dansensor® LeakPointer® 3+
    The leak detector Dansensor LeakPointer 3 and 3+ are designed for the food industry with a possibility to test leak sizes down to 50 µm. This helps ensure unwanted batch recalls and high product quality.
