Precautions for the purchase of a portable helium leak detector

Before making a decision, look for a wide range of applications.

For portable helium leak detector or helium mass spectrometer leak detector, it involves many industries and market segments. The vacuum system and all kinds of products and equipment require the leak test quality inspection process. Portable leak detectors are valuable and indispensable.

The following industries: automobiles; air conditioners; heating / refrigeration; SEMICONDUCTORS; electrical components; vacuum equipment; maintenance; pharmaceuticals; packaging; space; defense; energy; research and development; a number of examples are listed in the automotive sector: radiators, evaporators, fuel tanks, fuel caps and compressors, tires rim, air bag inflator And EGR, cooler, all of which require air tightness testing as part of the quality test. The choice of detection equipment is related to the success of detection.

Similarly, the air conditioning / heating / refrigerating Department has: compressor, condenser, heat exchanger, AC and room and outside device components, pressure control valves and Cooper all pipeline tests that need leakage. This is only a small list of equipment systems that require a sealed product.

Helium leak detector has not been "portable" since the 50s of last century, until the early years, when the semiconductor industry began to produce integrated circuits. The semiconductor industry began using the vacuum system to manufacture integrated circuit chips. It includes many system sputtering systems, chemical vapor deposition systems, evaporation systems, etch systems, ashing systems, and ion implantation systems are used in semiconductor manufacturing equipment. Air tightness detector is required to be small and portable. The clean room is relatively small, but the vacuum system is intensive. All these require high level of tightness and tightness. Today, portable leak detectors can be used in all industries mentioned above.

There are several points to note when buying there. There are three different ways and modes of leak detector.

The first mode is the use of external workpiece air tightness test pressure method.

The second is through the use of internal workpiece air tightness test pressure method.

The third is the "sniffer method", which includes helium, which is pressurized helium in the workpiece and detected outside the workpiece.

Therefore, you should consider these three methods to purchase the leak detector.
