Double-compensating and non-imaging optics (with 4-beam process). A large gas library with up to 38 substances (of which 27 substances are performance approved in accordance with DIN EN 50054/50057). Configurable measuring ranges in LEL % , Vol. -% and ppm. Fast response behavior, supported by the "chimney effect" of the splash guard.
