Absolute pressure decay leak tester T4990

leakagefor automationUSB

Overview
The T4990 ForTest is an absolute pressure-decay micro leak tester designed for integration in automatic, semi-automatic and rotary test benches. It provides a measurement resolution down to 0.1 Pa and supports optional metrological high-resolution mode (up to 1,000,000 points). The compact anodized-aluminium enclosure and optimized pneumatics reduce test volume and speed up cycle time. The unit is intended to replace custom assemblies of transducers, pneumatic units and PLCs for faster, plug&play integration.
