WIKA SF6 Gas Analyzer (GA11)

For determining the quality of SF6 gas


  • Analysis of the gas quality in gas-filled equipment
  • For the analysis of SF6 gas, g3 gas or N2 gas

Special features

  • Provides measured values for humidity, gas composition (purity) and decomposition products (optional)
  • Low transport weight of 25 kg
  • Three methods for emission-free treatment of the measurement gas:
    – Direct pumping back into the tested compartment
    – Pumping into an external gas cylinder
    – Collecting in an external gas bag
  • Battery power for min. 5 measurements or mains supply
  • Not compromised by transport restrictions (IATA)

The model GA11 SF6 Gas analyzer are innovative and reliable instruments for determining the quality of different insulating gases. Among these insulating gases are included SF6, Novec™ 4710 gas mixture (g3 gas) as well as applications for technical air (clean air/ dry air, based on oxygen and nitrogen). The SF6 Gas analyzer 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″ colourtouchscreen allow for intuitive operation. Sensors for the measurement of purity and humidity are included as standard. Optionally, the SF6 Gas analyzer 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 treatment of the measuring gas can also be carried out in the battery mode if mains voltage is not available.

Field use

The analytic instrument is protected from the harsh environmental 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.
