GASCHECK 340

Helium and Forming Gas 95/5 Mass Spectrometer Leak Detector for Industrial Use.

[Translate to Englisch:] GASCHECK 340 - Helium Massenspektrometer

The most straightforward operation in combination with an industrial design were the key features in the development of this series of new mass spectrometers such as the GASCHECK 340.

At a single push of a button, the leak detector starts the measuring program, regardless of whether it is a simple sniffing search or an integral leak detection in vacuum operation.

The compact leak detector can be mounted in control cabinets or close to the test station. In addition to the current measured values, diagrams of the leak tests can also be displayed and stored on the integrated SD card ("Leakage rate against time" and "Comparison of successive leak tests").

Thanks to the integrated PLC interfaces, the GC 340 can be easily integrated into simple as well as complex testing systems.

The integrated calibration leak is used for regular checking in integral operation. Measurement uncertainties are thus effectively prevented.

An oil-free version (GASCHECK 340 dry) with integrated diaphragm pumps is available as an option.

The GASCHECK 340 impresses with its powerful vacuum system, which has been designed to provide very quick readiness for operation. It is also characterized by a fast response time due to its high helium suction capacity. These features result in short cycle times and high part throughput.

The device is the only leak detector in its class on the market that is able to locate leaks from 100 hPa upwards.

A large selection of interfaces allows easy integration into production lines. The optional wireless remote control allows remote operation up to a distance of 100 metres.

Thanks to the robust construction and minimal maintenance, service costs are significantly reduced.

In conjunction with the ISM SMARTREMOTE PC-based test bench controller and the compact gas handling system (GHU) for controlling the entire evacuation and filling process of the test object, complete leak testing equipment can be set up with simple standard components.

Specific measurement solutions are developed for you in our department for fixture construction.
