VARIOTEC® EGA

Ethane gas analysis device

Fast, clear differentiation between natural gas and biogenic swamp gas through ethane detection
Analysis of methane, ethane and propane in a single measurement
Highly sensitive semiconductor sensor for very low concentrations in the ppm range
Integrated gas chromatograph for precise component determination
Intuitive operation via jog dial, soft keys and task-oriented menu navigation
Internal data storage with USB interface for PC-supported documentation
Reduces the risk of costly excavation errors

The VARIOTEC® EGA is a portable, easy-to-use measuring device for ethane gas analysis that reliably and accurately determines the gas components methane, ethane and propane. It lets you differentiate between natural gas and biogenic swamp gas on-site, avoiding costly excavations and laboratory analyses. Thanks to a highly sensitive semiconductor sensor and an integrated gas chromatograph, it delivers dependable results even at very low concentrations in the ppm range — all within rugged ATEX explosion protection and simple, task-oriented operation.
