Wika Canada Model GA11 Analysis instrument for determining the quality of SF6 gas

DescriptionWIKA SF6 Analysis of the gas quality of SF6 gas filled equipment

The SF6 gas analysis instrument model GA11 is an innovative and inexpensive instrument for determining the SF6 gas quality. Model GA11 can measure the concentration of up to seven parameters.

A clearly arranged menu structure and a 7" colour touchscreen allow for intuitive operation. Sensors for purity and humidity measurement are already built-in in the standard version. Optionally, model GA11 can be extended with a SO2 sensor for determining the SF6 gas decomposition products. In addition, four other sensor slots are available for retrofitting other sensors, e.g. for hydrogen fluoride measurement.

The measured SF6 gas can either be pumped back into the compartment of the switchgear or an external gas cylinder or it can be directly collected 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.

To evaluate the collected data, it is recommended to provide meaningful names for measuring points. With the GA11 it is possible to import a list of measuring points edited via PC quickly and easily.

Field use
The analysis instrument is protected by an impact-resistant and waterproof plastic case against harsh environmental conditions.
The hard-top case, which is designed for field use, is waterproof and has reels for facilitating transport and a telescopic carrying handle.
