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, using 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, kecepatan operasi yang cepat, high detection sensitivity and strong anti-interference ability.

Operasi sederhana

Stripping metal button, one-click automatic emptying. Hand-held remote control unit, hingga 150 meters remote detection. Ram wifi connection, noi tech app, remote control. Automatic zero-adjusting, automatic range switching. The custom software of the leak detector can be compiled according to the customer’s request.

Deteksi kebocoran

Metode tekanan negatif

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.

Metode tekanan positif

Ruang tertutup diisi dengan helium di bawah tekanan tertentu.

Ketika terjadi kebocoran, helium bocor melalui kebocoran melalui atmosfer sekitarnya .

Detection of helium concentration increments in surrounding atmosphere by suction method The precise location of the leak can be realized.

Metode tekanan balik

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;Ambil laju kebocoran maksimum untuk waktu tertentu.
