This professional, high-performance digital leak detector set has been specifically developed for the precise testing of leak-tightness in large volume battery enclosures. The safe and reliable operation of batteries in modern electric vehicles (EV) and hybrid vehicles (HEV) is critically important, and this device ensures the highest level of quality control during manufacturing and maintenance processes.
The set combines the latest technology with user-friendly handling, enabling fast and accurate detection of even the smallest pressure losses, thereby guaranteeing the integrity of battery insulation against moisture and contaminants.
This digital leak detection system offers several advantages over traditional methods:
High Precision Measurement: Digital sensors ensure extremely precise recording of pressure changes, minimizing the risk of false positive or negative results.
Fast Test Cycles: Optimized measurement protocols significantly reduce the time spent testing each battery enclosure, thereby increasing productivity.
Robust Construction: The device features a robust housing that meets strict workshop and manufacturing environmental requirements.
Data Management and Documentation: The digital display and internal memory enable the recording, storage, and later analysis of measurement data, which is essential for Quality Assurance (QA) processes.
Versatile Application: Optimized specifically for high-volume batteries, but flexibly adaptable for testing other large-scale pressurized systems.

The battery packs of electric vehicles feature complex cooling and heating systems (thermal management), which are often liquid-cooled. The integrity of these systems is of fundamental importance for thermal stability, fire safety, and the lifespan of the battery.
This digital leak detector set allows for the testing of closed cooling loop systems using the following methods:
Vacuum Testing: The system is capable of creating negative pressure (vacuum) in the tested volume. The time-based drop in the vacuum level is directly proportional to the magnitude of the leak. The digital display shows pressure stability second by second, enabling immediate calculation of the leakage rate (e.g., Pascal/minute).
Pressure Testing: The device is capable of applying positive pressure to the system (usually with an inert gas, such as dry air or nitrogen), and it monitors the pressure drop. This method is particularly useful for testing systems with higher operating pressures.
Advantage of Digital Technology: Unlike traditional analog manometers, which can cause reading errors, the digital system automatically records the measured values and can provide a visual or audible alarm if the pressure falls outside a preset tolerance limit. This drastically increases the objectivity and repeatability of the testing process.
This leak detector is the ideal tool in the following areas:
Battery Manufacturing: In-line Quality Control (In-line QC) on the production line.
Vehicle Manufacturing (OEM): Final inspection during vehicle assembly.
Services and Maintenance: Leak tests performed during the repair and refurbishment of high-voltage batteries.
Development and Validation: Testing and validation of new battery architectures.
Although a precise list of accessories is not available, professional kits of this type generally include the following, further increasing flexibility:
Adapters of Various Sizes: For connection surfaces of various sizes and types, ensuring compatibility with almost any battery housing.
Filling and Draining Valves: For the safe introduction and removal of the test medium (air/gas).
Data Acquisition Software: For models with PC connectivity, it enables graphical display and archiving of test results.
Carrying case: For the safe transport and storage of the device and accessories.
This digital leak detector set guarantees reliability, accuracy, and efficiency in inspecting critical components of electric mobility.
