LaserGas™ II Open Path is a compact, high performance gas monitor for ambient long distance monitoring. The LaserGas™ II OP consists of a transceiver and retro-reflector unit.
The retro-reflector unit consists of one or several cube corners in a weather proof enclosure, which reflects the light back to the transceiver. The detector collects the returned light for calculation of the gas concentration.
An optional auto-alignment unit can also be applied to ensure consistent alignment over time.
