How Sprint mD’s Comp & Cal Take the Guesswork Out of Leak Detection 

Leak testing is one of those things that has to be right every time—there’s no room for error when it comes to product quality, safety, and compliance. But as anyone in manufacturing knows, leak testing isn’t always straightforward. Changes in temperature, pressure, and environmental conditions can throw off results, leading to false failures or, worse, undetected leaks. That’s where Uson’s Sprint mD steps up. 

With its Compensation and Calibration (Comp & Cal) process, the Sprint mD isn’t just another leak tester—it’s a precision instrument designed to handle real-world manufacturing challenges. By eliminating environmental interference and ensuring leak rate measurements are accurate and repeatable, the Sprint mD helps manufacturers test faster, smarter, and with greater confidence. 

The Problem: Leak Testing Isn’t as Simple as It Seems 

At a glance, leak testing seems simple: pressurize a part, monitor pressure over time, and flag any drops as potential leaks. But real-world conditions complicate that process. 

Factors like ambient temperature, test part expansion, and the adiabatic effect—where rapid air compression temporarily increases temperature and pressure—can create pressure drops that mimic leaks. Without proper compensation, even leak-tight parts might “fail” the test. 

That’s why Sprint mD’s Comp & Cal system is a game-changer. 

Compensation: Filtering Out the Noise for Real Leak Detection 

The compensation step ensures that external factors don’t interfere with your test results. Before checking for leaks, the Sprint mD records the pressure characteristics of a known leak-tight part. It then uses this baseline to filter out environmental interference such as temperature shifts, part volumes, or minor fluctuations caused by the test process itself. 

Think of it like noise-canceling headphones: Instead of hearing everything around you, you get a clear, accurate signal. That’s exactly what the Sprint mD does, by subtracting out the expected behavior of a leak-free part, Sprint mD ensures that only leaks show up in the test.  

• Fewer false failures: You’re not rejecting good parts because of normal environmental changes.
• Less retesting and downtime: No more second-guessing whether a “fail” is legit.
• Confidence in every test result: When a part passes or fails, you know it’s because of the part itself, not testing inconsistencies.
  

Calibration: Making Sure Leak Rate Measurements Are Spot-On 

Pressure decay alone doesn’t define a leak rate—it must be calibrated to known standards. Sprint mD uses Leak Masters (precision devices with certified leak rates) to establish a clear relationship between pressure drop and leak rate (e.g., cc/min). While Compensation handles external interference, calibration ensures the leak rate measurements actually mean something. The Sprint mD runs a test using the Leak Master to establish the exact relationship between pressure drop and leak rate, ensuring every test result is properly calibrated. 

Here’s an example:

• A Leak Master certified at 4 cc/min at 60 psi creates a measured pressure drop of 0.2 psi in one minute.
• The Sprint mD now understands that this pressure drop equals a leak rate of 4 cc/min.
• Going forward, it can accurately convert any pressure drop into a precise, meaningful leak rate measurement.
  

This step is critical because most leak testers don’t inherently measure flow, they just detect pressure changes. Without calibration, you’re just guessing what those numbers mean. With the Sprint mD’s Comp & Cal, you get real, traceable, industry-compliant results. 

What This Means for Your Production Line 

By combining Compensation and Calibration, the Sprint mD eliminates guesswork and inconsistencies, giving manufacturers a leak testing solution that’s fast, accurate, and repeatable.

Here’s what that means for you: 

• Reliable leak testing in any environment – No more test results thrown off by temperature swings or pressure fluctuations. 
• Fewer rejected good parts and fewer bad parts slipping through – Better accuracy means better quality control. 
• Faster, more efficient testing – You’re not wasting time on unnecessary retests or debugging inconsistent results. 
• Confidence in compliance – Whether you’re meeting internal specs or industry standards, you can prove your tests are accurate. 

Leak detection shouldn’t be a guessing game, and with Uson’s Sprint mD, it doesn’t have to be. The Comp & Cal process ensures every test result is rock solid, so you can focus on keeping your products leak-free, your processes efficient, and your customers happy.
