NHJ-400 is a fully automatic mobile helium mass spectrometer leak detector with a simple structure and superior performance, suitable for many industries.
- Product overview
- Characteristics
- Technical Parameter
- Easy operation
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, fast operation speed, high detection sensitivity and strong anti-interference ability.
Performance characteristics
Unique gas path design, can avoid dust into the instrument interior
Multi-mode function input, output, easy to connect a variety of automation equipment
Double iridium ion source, strong antioxidant capacity and long service life
The machine is effectively separated from the circuit, avoiding the interference of temperature, electromagnetic field and so on, which makes the leak detector run more stable and reliable
