The Japanese ULAVC HELIOT 900 series helium mass spectrometer leak detector is the latest generation of helium mass spectrometer leak detectors launched

Product features:

High speed helium exhaust
In the micro leakage mode, the exhaust velocity of He reaches 5L/S, achieving rapid reduction of back pressure and system stability, and detecting small leakage points even with the addition of an auxiliary exhaust system.

High convenience touch screen
The 7-inch touch screen of the touchpad with electrostatic capacitance is used, and the display is completely separated from the main body, which can be matched with the most suitable layout usage method through the attached dedicated console. In addition, due to the wireless control mode connected to the main body, the remote control can be flexibly used.

Intuitive operation screen
Can perform simple operation, high-precision recognition, and easy testing interface

Can support multiple vacuum pumps: oil rotary pump, vortex dry pump

The 904 series is equipped with a convenient and easy-to-use trolley, while the 901 series also offers low chassis models

Excellent maintenance and upkeep, the panel can be easily disassembled, and the contact between various components is also very convenient. It is equipped with a user manual interface for operation

The vacuum method can detect not only helium gas but also hydrogen gas.

Product application scenarios:

Vacuum device airtightness inspection
Leak detection of various components such as pipelines and parts
Detection of helium and hydrogen flow rates and permeation rates
Product inspection of automotive components, air conditioning components, and heat exchanger components
Sealing inspection of packaging for food, pharmaceuticals, etc
