Custom Leak (Open Standard Leak) VTL-D Type
Key words: standard leak | MPCVD | capacitance film gauge vacuum gauge | high and low vacuum calibration device | helium leak calibration device
Classification:
Product Details
Open gas standard leak hole can specify pressure, leakage rate, etc. at the same time. Open standard leak hole does not have gas chamber or gas storage device. It needs external gas source and is suitable for any leak detector and leak detection system. Adopting advanced micro-channel technology, it has the advantages of fast response, small temperature drift (glass penetration is 3%/℃, channel type is 0.2/℃), small leakage rate and not easy to block, wide leakage rate test range, can be used with or without storage gas tank, firm structure, non-vulnerability and good stability.
