Leak and Flow Testing Systems from ForTest
The established range of ForTest products include the “Basic Absolute“ Pressure Decay Leak Testing, an “Advanced Absolute” Pressure Decay Leak Testing, and an “Advanced Differential” Pressure Decay Leak Testing, (using a reference volume), as well as a “Flow Testing” System.
The latest development by ForTest is their “Advanced Dual Absolute” Pressure Decay Leak Test System. This utilizes a reference volume, however the cycle time is not extended, as the testing is performed with 2 pneumatic circuits. This provides the stable readings over the course of the cyclic operation.
The experienced team at A-Tech Instruments Ltd. can help to identify the correct solution for your leak test requirements.
These systems use high quality, zero leak valves to create a robust and durable system. Different configurations are suitable for different types of applications.

“Dual” Absolute Pressure Decay Leak Testing
The new Dual Absolute technology makes it possible to eliminate the disadvantages of a classic differential system. Thanks to the new Dual Absolute technology, ForTest has combined the simplicity of a classic absolute decay system with the precision and sensitivity of a differential system, bringing leak testing instruments to a level never seen before.
The new algorithms and measurement hardware eliminate typical defects in a differential system, such as differences in stabilization between the test part and the reference sample.
The new range of instruments is able to work in 3 different ways: Pure Differential, Dual Absolute and Central Zero. The “Zero Center” technology allows for testing of two components simultaneously, doubling productivity

Custom Leak Test Fixtures by A-Tech Instruments
As a value-added distributor, A-Tech Instruments Ltd. offers the capability to build custom manual or automatic leak test fixtures to ensure the sealing and integrity of various parts. Our tailored solutions meet the unique requirements of each application, providing robust and reliable leak testing systems that enhance quality control and safety.
Case Study: Innovating Leak Testing System for Battery Covers
Leak testing for battery covers is crucial in ensuring the longevity and safety of batteries, especially in applications such as electric vehicles (EVs) where performance and reliability are paramount. Proper sealing of battery covers prevents potential leaks that could lead to performance issues or safety hazards. Building a reliable and effective sealed fixture is essential for accurate and efficient leak testing.
Understanding the importance of this, A-Tech Instruments developed an automated system to test the seal integrity of battery covers used in electric vehicles (EVs). This system was designed to streamline the testing process and deliver precise, reliable results.
Using a sophisticated setup involving a PLC-controlled environment, the system featured advanced T8990 leak testers capable of handling multiple tests simultaneously. The inclusion of a bank of valves allowed for precise airflow control, crucial for accurate leak detection.
The process begins with the operator placing the battery cover onto a custom-designed fixture that ensures it is securely held in place. With a simple push of a button, the automated system engages, clamping the cover and initiating the testing sequence.
This system not only performs initial group tests to quickly identify any potential leaks but also has the capability to focus on specific areas if a leak is detected. By streamlining both the overall and targeted testing processes, the system efficiently pinpoints issues without the need for extensive manual intervention.
Key features of this system include its automated clamping mechanism and the ability to simultaneously test multiple vents, enhancing both the speed and accuracy of the testing process. The data collected is integrated seamlessly, providing a comprehensive overview of each test, and ensuring high-quality standards are met.
