T6990

Entry-level absolute decay air leak tester

The T6990 represents the ideal solution for those seeking air leak testing equipment with absolute pressure decay that is compact, immediate and reliable. Heir to the renowned M6990 model, this device elevates the standard of the “entry-level” category by offering measurement precision comparable to higher-end models.

Widely known in the biomedical sector as “test head”, it represents a reference point in clean room leak testing for performance, operational speed and reliability.

Below are some of its main features:

  • Ultra-compact pneumatics
  • Rapid interfacing
  • HMI Touchscreen

The High-Performance Entry-Level Equipment
The T6990 represents the ideal solution for those seeking an absolute decay leak tester that is compact, immediate and reliable. Heir to the renowned M6990 model, this device elevates the standard of the “entry-level” category by offering measurement precision comparable to higher-end models.A

Modern and Robust User Interface
The equipment stands out for its elegant and functional design, featuring a front panel made of tempered glass and aluminum, extremely easy to clean. It integrates a high-resolution 3.5″ color display and a capacitive keyboard that make parameter prograHMIng and test cycle visualization clear and fast.

Pneumatic Mechanics and Zero Maintenance
To maintain compact dimensions, the T6990 features a pneumatic assembly with standard flow valves, ideal for testing volumes up to 5 liters. The robustness of the components is designed to eliminate the need for scheduled maintenance, ensuring concrete savings on operational costs.

Complete Connectivity for Traceability
Despite its compact format, the interface equipment is complete for every industrial need:

  • Serial Port: RS232, RS485, USB (CDC)
  • Data Management: Front USB port (Mass Storage) for saving tests on USB drive, parameter backup/restore and firmware updates.
  • Automation: Automatic connection to thermal printers and barcode/data-matrix readers through internal menu.

Measurement Precision
The T6990 boasts a measurement resolution of 0.1 Pa at 1 bar (0.5 Pa at 6 bar), stable and free from electronic noise. It supports pressure scales ranging from -1 to 10 bar, making it versatile for numerous application sectors.
