Introduction: ZLS-24D / M helium mass spectrometer leak detector (hereinafter referred to as the instrument): Turbomolecular turbocharger used as the main exhaust machine, start fast (only five minutes to use). Instrument can be used in the test port pressure is about 1000Pa, reverse leak detection leak detection method can also be used when the pressure in the test port is better than 50Pa leak detection in the conventional way; leak detection with the conventional way, you can divert the state Under the leak (test port pressure in the 50 ~ 10-1 Pa), can also be split in the state of tiny leaks (test port pressure better than 10-1Pa). The instrument can automatically find the peak, easy reading, audio alarm device. Technical Parameters: Instrument start-up time: not more than 5min Minimum leak rate: better than 1 × 10-11Pa.m3 / s (negative pressure method) Reaction time: not more than 3s Mass spectrometry room to work the maximum pressure: 1 × 10-2Pa Test port to allow the maximum pressure of work: 1000Pa Leak detection interface: KF25 Instrument outline size: 640 * 550 * 980 mm3 The weight of the instrument: about 75Kg The main configuration: a turbo molecular pump Pre-level mechanical pump one Rough pumping mechanical pump one Calibration leak 1 (with measurement verification certificate) Mass Spectrometry Room 1 (Chengdu Instrument Factory) Control circuit and solenoid valve (Chengdu Instrument Factory) Industrial computer 1 Taiwan A spray gun (Chengdu Instrument Factory) ZLS Helium Mass Spectrometer Leak Detector Control and Analysis System V1.0 Instrument power supply: 220V ± 10%, power is about 2Kw
Helium mass spectrometry leak detection technology is an indispensable technology in the field of vacuum leak detection. It is easy to operate due to high leak detection efficiency. The Helium mass spectrometer leak detector is sensitive, high precision, and is not easily interfered by other gases. The Helium mass spectrometer leak detector has been widely used in resistance furnace leak detection. The helium mass spectrometer leak detector is a gas tightness detecting instrument made of helium gas as a leak gas according to the principle of mass spectrometry. The helium mass spectrometer leak detector consists of an ion source, an analyzer, a collector, a mass spectrometer chamber composed of a cold cathode ionization gauge, an extraction system, and an electrical part.
