High Precision Vacuum Leak Detector for Vacuum Systems
Helium mass spectrometer leak detector is advanced in technology, stable in performance, small in size, light in weight, convenient in use, high in reliability, complete in equipment, new in function, remote-controlled pump, powerful in function, providing leak detector equipment with small volume, convenient in operation and high in reliability. ZQJ-560 helium mass spectrometer leak detector is a detection instrument with high sensitivity, high reliability and advanced operation technology. With years of experience in the development of helium mass spectrometer leak detector, we have independently developed a new type of helium mass spectrometer leak detector by absorbing advanced foreign concepts. The overall design of the instrument reflects the company's independent technological innovation capability, and is suitable for various occasions requiring high sensitivity leak detection.
Product features
High sensitivity: The sensitivity of the instrument is superior to that of similar products, and it can detect very small leakage.
High reliability: long life yttria iridium filament and imported composite molecular pump are used to ensure the instrument can still operate stably under harsh working conditions.
Advanced operating technology: equipped with PLC operating system and color touch screen display, simple and intuitive operation. At the same time, the instrument has the functions of one-key operation, full-range calibration, rapid start-up and cyclic detection, which improves the detection efficiency.
Multiple leak detection methods: Normal, Gross and Sniffer leak detection methods are provided, and the leak detection sensitivity covers 12 orders of magnitude to meet different detection requirements.
Helium pollution prevention function: The instrument has its own helium pollution prevention function to ensure the accuracy of the test results.
