When performing vacuum method leak tests on equipment such as large chambers or long piping, the detector often can't provide sufficient pump evacuation capacity by itself. In this case, the equipment being tested must be evacuated by its own evacuation system or by a separate evacuation system. HELIOT model 103 is a leak tester for equipment maintenance using the vacuum method. It does away with inadequate rough evacuation pumps, and offers high-precision testing in a compact/space-saving, low-cost design.
