WIKA Alexander Wiegand SE & Co. KG from Klingenberg is a German, internationally active family business that primarily manufactures pressure and temperature measurement technology, proving itself to be a driver of innovation in the industry. WIKA's latest achievements include the next generation of the GA11 gas analyzer. According to the supplier, it enables switchgear operators, manufacturers and maintenance companies to record the quality of SF6 gas and alternative insulating gases. The GA11 provides precise measured values for humidity, gas purity and decomposition products. Temperature-compensated sensor technology and intelligent measurement algorithms based on stability criteria are designed to ensure maximum accuracy in the measurement of purity and dew point - a significant improvement on all previous versions. Optional sensor technologies for sulphur dioxide, hydrogen fluoride, hydrogen sulphide and carbon monoxide also offer high accuracy and long-term stability.

According to WIKA, the new GA11 is suitable for mobile use thanks to its lighter and more compact design. The weight of the impact-resistant hard case, which is protected against water jets and dust in accordance with IP65, is just 22 kilograms. An integrated nickel-metal hydride battery (NiMH) is also an advantage here. Unlike devices with a lithium-ion battery, the GA11 is not subject to the transportation restrictions of the International Air Transport Association (IATA). The device can be carried on the plane as checked baggage - a plus point for international use.

Thanks to the intuitive user interface and clear menu navigation, all measurement processes are easy to control. All functions of the GA11 are available in both battery and mains operation. Last but not least, a closed measuring system reliably prevents emissions into the atmosphere: the sample gas is either fed back into the gas chamber or collected in an external gas recovery bag.
