The model GA11 analytic instruments are innovative and reliable instruments for determining the quality of different insulating gases. Among these insulating gases are included SF6, C4-FN gas mixture (g3 gas) as well as applications for technical air (Clean Air / Dry Air, based on oxygen and nitrogen). The model GA11 can measure the concentration of up to six parameters, depending on the selected equipment variant.
Set up
A clearly arranged menu structure and a 7\" colour touchscreen allow for intuitive operation. Sensors for the measurement of purity and humidity are included as standard. Optionally, the model GA11 can be extended with electrochemical sensors for determining the SF6 gas decomposition products.
The measured gases can either be pumped back into the gas compartment of the switchgear or an external gas cylinder or, alternatively, it can be collected directly in a gas bag. In each case, emission into the atmosphere is avoided. The described handling of the measuring gas can also be carried out during battery operation if mains voltage is not available.
Field use
The analytic instrument is protected from the harsh ambient conditions through an impact-resistant and waterproof plastic case. The hard-top case, which is designed for field use, is fitted with wheels and a telescopic carrying handle for ease of transport.
