Industrial Applications

1. Precise Pick & Place Vacuum Monitoring

Used in conjunction with vacuum grippers handling miniature electronic components, providing micro-flow verification.

Problem Solved

Eliminates false positives by precisely verifying micro-flow blockages (0.002 L/min) indicating a tiny object is firmly secured, rather than relying strictly on macro-level pressure switches.

2. Micro-Leakage Detection in Assembly Verification

Deployed at the end of manufacturing lines to check micro-leaks in sealed medical devices, pneumatic valves, or cylinders.

Problem Solved

The highly sensitive thermal heat transfer measurement identifies minute air escapes (down to 0.002 L/min) to determine if seals pass stringent quality assurance tests.

3. Medical & Inert Gas Dosage Control

Real-time verification of trace gas flows for precise mixing or dosing applications within automated laboratory environments.

Problem Solved

The low volumetric range exactly measures ultra-low gas volumes to prevent under-dosing or overdosing in critical protective gas environments.
