WIKA has launched the next generation of its GA11 gas analyzer. 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 sensing technology and intelligent measuring algorithms based on stability criteria ensure maximum accuracy when measuring cleanliness and dew point. Optional sensing technologies for sulphur dioxide, hydrogen fluoride, hydrogen sulphide, and carbon monoxide also offer high accuracy and long-term stability.
The new GA11 is suitable for mobile use thanks to its lighter, more compact design. The weight of the impact-resistant hard case, which is protected against water jets and dust in accordance with IP65, is 22 kilograms. An integrated nickel-metal hydride (NiMH) rechargeable battery is also an advantage here. The instrument can be carried on aircrafts as checked baggage.
Thanks to an intuitive user interface and clear menu navigation, all measurement processes are easy to control. All functionalities of the GA11 are available in both rechargeable-battery and mains operation. Last but not least, a closed measuring system reliably prevents emissions into the atmosphere; the measuring gas is either returned to the gas compartment or collected in an external gas recovery bag.
