EHLD-400 Helium mass spectrometer leak detector is a leak detector with high sensitivity, fast speed and wide range. It consists of turbine high vacuum molecular pump, built-in mechanical pump, external mechanical pump, mass spectrometry chamber, valve seat components, circuit boards, operation panels and other optional functional components. Helium mass spectrometer leak detector is an instrument used to locate and quantify leakage points of sealed objects. It uses the inert helium gas, which is non-toxic, inert, low in atmospheric content and low atomic weight, as the detection gas. The gas can easily pass through the leakage hole and it is non-flammable safe gas which can be stored in bottles and cans of all sizes. It is widely used in many fields.

Advantages:
1.Using metal button,one-clickautomatic emptying.
2.Hand-held remote control unit,up to 150 meters remote detection(optional with additional cost). 3.Unique gas path design,can avoid dustinto the instrument interior.
4.Multi-mode function input,output,easy to connect a variety of automation equipment. 5.Double iridium ion source,strong antioxidant capacity and long service life.
6.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.
7.Automatic zero-adjusting,automatic range switching.
8.The custom software of the leak detector can be compiled according to the customer’s request.
9.Large leak detection function:The pressure can be preset.When the pressure is evacuated,if the preset value cannot be reached,the leak detector willautomatically alarm.
10.Multiple measurement unitselections,real-time updates of detection data,and direct output to generate Excel tables.
11.Rotatable,7-inch color touch screen,the operator can adjust the direction according to comfort.
12.Large leakage protection mode fully protects the ion source from oxidation and the molecular pumpfrom being impacted when exposed to the atmosphere.
