Function description and advantages
The unique gas circuit design improves the pumping speed of helium, shortens the time of clearing helium background, and effectively prevents helium pollution.
The leak detection port is equipped with a customized precision filtering device, which can effectively prevent foreign particles or copper powder from entering the instrument.
Multi-mode function input and output, easy to connect various automation equipment.
The mechanism and circuit are effectively separated to avoid mutual interference of temperature and electromagnetic field, so that the leakage detector operates more stable and reliable.
The minimum detectable leakage rate is low, the sensitivity is high, and the detection range reaches level 11.
Convenient operation
Stripping metal button, one-click automatic emptying.
Hand-held remote control unit, up to 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.

Helium mass spectrometer leak DX200
The helium mass spectrometer leak detector is an instrument that can quickly locate and quantitatively measure the leakage of sealed containers. Compared with bubble identification method, pressure attenuation method and halogen leak detection method, helium mass spectrometer leak detection method has high detection sensitivity, fast speed and wide application range. In addition, helium mass spectrometer leak detector selects non-toxic, non-destructive and light inert gas helium as the exploration gas, so it is safe and reliable
