Main applications of air tightness testers: electronics industry, hardware processing industry, mobile phone industry, watch industry, aerospace, medical devices, smart industry, smart home product industry, protective equipment industry, fire protection products, auto parts industry, and sealing tests for various precision component interfaces.
Sealing performance refers to the reliability of the product interface seal. This testing instrument ensures the sealing integrity between the entire product interfaces, preventing issues such as leakage, contamination, water seepage, and water erosion caused by poor sealing performance of the product.
Test pressure:
Used to set the maximum pressure value for inflating the container under test. When this pressure value is reached, the instrument stops inflating and enters
Pressure equalization procedure.
Balance time:
Used to set the pressure equalization time between the tested space and the reference space after inflation ends.
Leak pressure value:
Used to set the allowable leak pressure value for the product under test. If, during the pressure holding process, the differential pressure between the pressure inside the tested container and the analysis pressure of the standard container is greater than this value, it will be displayed as failed (NG); if it is less than this value, it will be displayed as passed (OK).
Number of products tested:
Used to set the quantity of test products. When the set output is reached, the system will pop up a prompt to notify the user.
Production completed. You can press the "Clear" button below to reset the set quantity.
Pre-evacuation:
This is the exhaust time set before the test program to prevent residual air pressure in the container under test from affecting test accuracy before inflation. It is generally set to 1 second. The actual setting depends on specific conditions; if set to 0, the program will skip this step automatically.
Inflation time:
Used to set the time for inflating the container under test. Once the pressure reaches the set value, the instrument automatically proceeds to the holding program, regardless of this time limit. If the container is still not fully inflated when the time expires, NG is displayed directly to save testing time.
Hold time:
Used to set the holding time for the pressure inside the container under test. When the time is up, if the internal pressure is equal to or greater than the lower limit pressure
If it shows OK, and if the pressure drops below the lower limit during the hold pressure process, it will directly show NG.
Pressure release time:
Used to set the time for discharging the gas from the container under test after the test program is completed; it is often used in applications with relatively high test pressure to prevent danger or damage to the workpiece when opening the fixture or removing the workpiece under high pressure.
1. User-friendly operation settings interface: The UI features guided operation, making it simple and easy to understand without the need for in-depth learning.
2. Air source overpressure alarm: prevents damage to the instrument and the product under test caused by abnormal manual pressure regulation.
3. Instrument self-check function: it can test the instrument's internal piping to prevent misjudgment caused by leakage of the instrument itself.
4. Instrument appearance: clean and elegant, compact size that saves space.
5. Pneumatic valve manifold: The pneumatic valve manifold is independently developed by our company, offering high reliability.
6. High-end models use imported pressure sensors to ensure testing stability.
