Description
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 mixtures and also applications for natural origin gases (gas mixtures based on nitrogen, oxygen and carbon dioxide). The model GA11 can measure the concentration of up to six substances, depending on the selected equipment variant.
Special features
- Provides measured values for humidity, gas composition (purity) and decomposition products
- Intelligent measurement based on the stability criteria of the sensing technology
- Temperature compensated sensing technology
- Not subject to any transport restrictions (IATA)
