Digital Static Tester
The Digital Static Tester (DST) from Stein Seal is a specialized device used to accurately measure and instantly display the leakage rate of any static seal. The DST permits precise, real-time evaluation of seal performance under pressure without disrupting the seal faces, providing instant insights into the effectiveness of any stationary seal in preventing fluid or gas from leaking out of the system. Put the Digital Static Tester to work whenever you’re designing, constructing, installing, evaluating, or troubleshooting a static seal of any kind.
- Enhance Quality Control—Test new seals to ensure they meet performance standards before installation, reducing the risk of premature seal failure.
- Prompt Failure Analysis—Investigate the severity and cause of a leak in-house, reducing guesswork, downtime, and resulting costs.
- Informed Material Selection—Compare different seal materials to determine the best option for a specific application.
Advanced Static Seal Testing Equipment
Stein Seal combined decades of experience with advanced technologies to design a compact, lightweight, and flexible static seal tester that provides instant and accurate results under pressure. Stein Seal’s Digital Static Tester utilizes advanced programming and sensor technology to accurately measure seal leakage with precise air pressure and flow rate control, providing a quantitative value of the seal’s effectiveness.
Accurate Results in Real Time
Unlike older testing methods, the Digital Static Tester provides a precise, easily readable measurement of the leakage rate, allowing for better quality control and real-time analysis. The DST system software analyzes the mass flow rate corrected to the selected units. It displays the results on an integrated digital display in real time, utilizing actual temperature, absolute pressure, and volumetric flow rate. Test data can also be instantaneously downloaded to any computer connected through the incorporated port.
Universal Static Seal Compatibility
The DST is specifically designed for static seals of all types and sizes and applications where there is no relative motion between faces. Specialized fixtures, tailored to the seal type and application, safeguard the seal during testing and ensure consistently accurate measurements in both new and refurbished seals. Programmed to calibrate to any of the 16 specific types of gas and compatible with fluid systems, Stein Seal’s Digital Static Tester is the flexible solution for rapid static seal testing.
Customizable Features
Digital static testers, both tabletop and portable models, are pre-calibrated to meet unique application requirements, with customizable features that facilitate accurate, reliable results regardless of static seal type or size. These features include:
- Custom testing fixtures tailored to specific components, seals, and systems.
- PSI and SI unit digital pressure gauge configuration options.
- Customer-specified air pressure and flow ranges.
- Recalibration services to support scale
Portable Digital Static Tester
The DST’s compact and lightweight design allows the unit to be securely housed in a durable case no bigger than a typical piece of carry-on luggage. Manufactured from industrial polypropylene, the protective case is watertight, dustproof, and crushproof, allowing for efficient and accurate field testing of static seals in the harshest conditions.

Tests More Than Just Seals
In addition to evaluating static seal performance, Stein Seal’s Digital Static Tester offers valuable versatility across a range of pressure-critical applications. Its precise flow control, customizable settings, and real-time digital readout make it an asset in environments where reliability and consistency matter. Beyond static seal testing, the DST can be used to:
- Perform leak testing on valves, fittings, enclosures, and other sealed components.
- Compare seal materials under identical pressure and flow conditions during R&D.
- Troubleshoot in-service leaks to pinpoint failures and reduce downtime.
- Validate pressure and flow sensors against a known, accurate reference.
- Evaluate the compression behavior of components under load.
- Detecting fixture or housing deflection under pressure.
- Analyze torque retention and seal memory after simulated service conditions.
Whether you’re working in quality control, product development, or system maintenance, the DST delivers actionable insights with speed and precision. Contact Stein Seal to learn how the Digital Static Tester can support your application.
