Sealed packs are placed into the water bath, a soft close hinged lid submerges them below the water level. An isolation switch is opened causing the pack internal pressure to increase to the pre-set pressure. The operator observes the packs through the chamber walls, a steady stream of bubbles indicates the location of any leaks. Burst testing can be conducted by gradually increasing the pressure and observing the pressure gauge when the pack opens.
- Leak / Seal integrity tests to pre-set pressures.
- Burst testing to determine seal strength.
- No trace gas in pack needed, no mains electric, semi-portable.
- Simple & fast for quality control.
- Drain / Fill valve, convenient for regular change of water.
- Various water tank sizes
For ASTM F2096, BLT-Pxxx is supplied with needle / septums. Includes dial pressure gauge, or upgrade to a digital pressure controller (Lippke 5000 with Bubble test method).
