TIGHTChecker - Tightness Testing

Overview

TIGHTChecker is an ultrasound detector designed specifically for tightness testing. A focused solution for inspecting seals, gaskets, tanks and airtight joints.

Applications

Tightness testing

TIGHTChecker is used to check:

• Tank tightness — fuel, chemical, water tanks
• Door seals — hatches, airlocks, gates
• Gaskets — flanged connections
• Windows and display cases — frame tightness
• Enclosures — water resistance

Testing method

Ultrasonic transmission method

1. An ultrasonic emitter is placed inside the test object
2. TIGHTChecker scans from outside
3. Leaks are detected by ultrasound seepage

Advantages of the method

• Sensitivity — detects microscopic leaks
• Speed — fast inspection of large areas
• Accuracy — precise fault localisation
• Safety — non-invasive method

Application areas

Marine industry

• Ship hatches — deck-hatch tightness
• Portholes — seal inspection
• Watertight bulkheads — tightness control
• Airlock doors — water resistance

Industry

• Tanks — fuel and chemical tanks
• Vessels — liquid storage
• Pipelines — flanged connections
• Valves — seat tightness

Automotive industry

• Cabin tightness — sound insulation
• Door seals — water protection
• Sunroof — seal inspection
• Bonnet and boot — seal control

Pharmaceuticals and cleanrooms

• Isolators — glove-box tightness
• Laminar-flow cabinets — seal monitoring
• Cleanrooms — door seals
• Containers — shipping crates

Construction

• Window frames — tightness
• Display cases — seal inspection
• Doors — closure control
• Roofing — leak detection

Economic impact

Losses from leaks

• Product leakage — direct financial losses
• Contamination — environmental fines
• Equipment damage — corrosion, short circuits
• Energy — heat or cold losses

ROI

• Pays for itself on the first detection
• Prevents incidents
• Ensures standards compliance

Standards and regulations

TIGHTChecker helps meet:

• ISO — tightness standards
• FDA — pharmaceutical requirements
• Marine standards — classification societies
• Environmental regulations — leak prevention
