Leak Tester, Differential Method


T3LD is an innovative device for leak tests by pressure differential method.

Flow and leak tester

T3LD is an innovative device for leak tests by differential pressure method. By measuring the pressure difference between the product being tested and a reference sample, it is possible to reduce test time and heighten the sensitivity.




­­The touchscreen interface, with a colour display and the real-time visualization of the tests, makes the programming and the use simple and immediate.

Its high measurement resolution and the test accuracy, in combination with the electronic regulation of the filling pressure, allow to perform not only leak tests but also destructive burst tests, safety valves opening checks, volumetric control, obstruction tests and “in bell” tests on sealed products or by interception method.




T3LD has digital I/O interfaces to PLC connection, USB host, two serial lines RS485/RS232 for PC, Ethernet interface. The control of external automations, the interface with barcode, QRcode readers and printers make T3L a complete and suitable instrument for the most modern production applications. The software manager dedicated permits to collect and manage data of the tests, to set up the parameters programming and do SPC analysis of tests data.

  • Leak test full-scale ranges: up to 30 bar and vacuum
  • High measurement resolution: up to 0.1 Pa
  • Colour 7” LCD display – graphic test view
  • Fully Interfaceable: Digital I/O for PLC – USB for PC – Serial lines RS485/232 - Ethernet
  • Test Data Storage on USB pen drive or LAN/Ethernet/Profinet
  • External Automations and devices control: printer, barcode and QRcode reader – remote control keypad – external valve for volume check and tests in sealed ‘bell’ – air filters
  • Software Manager, dedicated for T3 equipment management data storage and statistical process, is available.
