Product Details

NOYNuoyiHelium mass spectrometer leak detector（NHJ400series）

NHJ400The series helium mass spectrometer leak detector is a fully automatic mobile helium mass spectrometer leak detector with a simple structure and excellent performance, suitable for many industries.

Applied helium mass spectrometry and reverse diffusion principle,adopted180Non uniform magnetic field and fully automatic control technology have achieved automatic helium peak scanning, automatic zeroing, and automatic range switching,It has the characteristics of fast detection speed, high detection sensitivity, and strong anti-interference ability.

Large leakage detection function: By setting the pressure, if the preset value is not reached during evacuation, the leak detector will automatically sound an alarm prompt.

Multiple measurement units to choose from, real-time updates of detection data, and direct output to generate tables.

Multiple large leakage protection modes fully protect the ion source from oxidation and prevent the molecular pump from being impacted when exposed to the atmosphere .

Performance Characteristics

lThe unique gas path design improves the pumping speed of helium, shortens the background time for helium cleaning, and effectively prevents helium pollution.

lLeak detection port equipped with customized precision filtering device, which can effectively prevent foreign particles or copper powder from entering the interior of the instrument.

lMulti mode function input and output, easily connecting various automation devices.

lThe effective separation of machinery and circuits avoids interference from temperature, electromagnetic fields, etc., making the leak detector operate more stably and reliably.

lThe minimum detectable leak rate is low, the sensitivity is high, and the detection range reaches11Grade.
