KYKY (Beijing KYKY Technology Co., Ltd.), China's leading vacuum and leak detection equipment manufacturer, offers a comprehensive range of Helium Mass Spectrometer Leak Detectors. The primary product line, the ZQJ series, supports leak detection in vacuum mode, spray mode, and sniffing mode. These detectors are ideal for various industries, including semiconductor manufacturing, automotive, aerospace, refrigeration and air conditioning, and chemical metallurgy. The series includes portable, tabletop, and modular models. While some older models have been discontinued, they may still be available through maintenance services or the second-hand market. Below is a detailed list of KYKY Helium Leak Detector models, compiled from official catalogs and supplier information, categorized into current/active and discontinued models, along with their key features (e.g., dry/wet, main applications). This list covers major variants but is not exhaustive.
These models are still sold or supported on the KYKY official website and by suppliers. They emphasize high sensitivity, fast response, and the use of localized components, such as proprietary turbomolecular pumps. For more information on advanced vacuum solutions, visit our main site.
