EVTECH จำหน่ายเครื่องเช็ครอยรั่วด้วยก๊าซฮีเลียมขนาดเล็ก (Helium leak detector)
CANON ANELVA's leak detectors are used in a variety of quality control applications requiring high sealing performance.
These products that emphasize operability are highly regarded by our customers in a variety of industries.
Helium Leak Detector
Canon ANELVA produce helium leak detector which can measure wide range leake rate.
Measurement range is 10E-2 to 10E-13Pa·m3/s.
Helen series is a helium leak detector measuring by Spray method or Envelope method or Sniffer method,
Helen series measures leak quantity in a high repetability and quick rersponse.
It is used for the leak test of various parts, electronic parts, computer parts, automobile parts, a parts for refrigerator or heat exchange.
The reason why helium gas is suitable for leak test.
- Helium gas exists only 5ppm in the atmosphere, it is easy to distinguish from other gas.
- The diameter of helium gas is 2.18A, helium is the smallest gas.
- Helium is inert gas, is hard to adsorb and is harmless.
Helium Leak Detector HELEN Series M-212LD(-D)/M-222LD(-D)/M-232LD
The HELEN series consists of compact, light-weight, portable design helium leak detectors.
