TIGHTChecker
A precision ultrasound tool for tightness testing and leak detection
Starting at:
$2,795
The TIGHTChecker is SDT’s purpose-built ultrasound solution for tightness testing. It helps you verify the integrity of enclosures, compartments, and pressurized systems using airborne ultrasound and an integrated ultrasonic tone generator.
Simple, reliable, and built for everyday inspections, TIGHTChecker allows operators to detect leaks around doors, hatches, cabins, and seals, confirming that assets are airtight, watertight, and energy efficient.
TIGHTChecker uses an ultrasonic tone generator placed inside an enclosed space. The generator emits a steady, high-frequency tone that TIGHTChecker detects from the outside. Any sound that escapes indicates a leak path—making it easy to pinpoint exactly where air or water can get in or out.
It’s ideal for testing the tightness of ship and vehicle cabins, control rooms, cargo holds, HVAC ducts, electrical enclosures, and other sealed compartments. It’s also used to confirm door and gasket integrity after maintenance or cleaning.
No. It’s simple to use and ready out of the box. For anyone who wants to learn more about tightness testing, free self-paced courses are available through SDT.training.
Why Work with SDT
Tightness Testing and Why It Matters
Air and water leaks are more than an inconvenience… they compromise safety, comfort, and energy efficiency. Leaky compartments allow moisture, dust, or contaminants to enter, while escaping conditioned air increases energy costs and system strain.
Traditional testing methods like smoke or pressure tests can be messy, time-consuming, and inconsistent. Ultrasound testing with TIGHTChecker provides a fast, clean, and repeatable way to verify seal integrity with precision.
By identifying leak paths before they become costly problems, you extend asset life, improve energy performance, and ensure safety standards are met across your facility or fleet.
Operator-Driven Tightness Testing
Tightness testing fits perfectly into SDT’s Operator-Driven Safety and Reliability (ODSR) approach. With TIGHTChecker, front-line operators can verify the integrity of enclosures, doors, and compartments as part of their regular inspections.
When operators take ownership of tightness testing, leaks are found earlier, safety and efficiency improve, and systems remain sealed and reliable for longer.
Benefits of an ODR Approach to Tightness Testing
Confirm that gaskets, doors, and enclosures are properly sealed before returning equipment to service.
Keep sensitive components protected from contamination and corrosion.
Eliminate air leaks in HVAC systems, cabins, and compartments to improve efficiency and comfort.
Ensure safety-critical enclosures maintain the correct level of protection from external conditions.
Reduce waste, improve air retention, and keep assets performing at peak efficiency.
