NHJ600 Series Helium Hydrogen Mass Spectrometer Leak Detector Vacuum helium leak detection analyzer
Performance description
NHJ-600 series leak detector is a fully automatic mobile helium mass spectrum leak detector, mute wheel design, suitable for many harsh vacuum industry.
Using helium mass spectrometry and inverse diffusion principle, استخدام 180 ° inhomogeneous magnetic field and automatic control technology. Automatic helium peak scanning, automatic calibration and automatic range switching are realized.
It has the characteristics of short start time, fast operation speed, high detection sensitivity and strong anti-interference ability.

عملية بسيطة
Stripping metal button, one-click automatic emptying. Hand-held remote control unit, يصل إلى 150 meters remote detection. Ram wifi connection, noi tech app, جهاز التحكم. Automatic zero-adjusting, automatic range switching. The custom software of the leak detector can be compiled according to the customer’s request.
Leak Detection
Negative pressure method
Vacuum the sealed chamber inside the inspected product Apply helium gas on the outer surface of the product under inspection Leak detector detects changes in helium content inside the workpiece The precise location of the leak can be realized.
Positive pressure method
The sealed chamber is filled with helium under certain pressure.
When a leak occurs, helium leaks through the leak through the surrounding atmosphere .
Detection of helium concentration increments in surrounding atmosphere by suction method The precise location of the leak can be realized.
Back pressure method
Place the inspected product in a pressurized helium chamber for a certain period of time Remove the residual helium from the surface Put the inspected product into the leak detector connected with the leak detector;Take the maximum leakage rate for a certain time.
