NEO Monitors LaserGas II Open Path (OP) Monitor is s a compact, high performance gas analyser for long distance monitoring in ambient air. Measurement lengths of up to 1000 m one way are possible. The OP Monitor utilizes a transmitter / reflector configuration to measure the average gas concentration along the optical line-of-sight. As option a self-contained, battery-powered version is available with a control keypad and a flash memory for data logging.
The monitor is installed on our proprietary x/y alignment platform (goniometer). Adapters for fixed installation on platforms or for tripod use are available. The instrument also includes a visible aiming laser and sighting optics for easy alignment even over long distances. Hoods for protection of the optical windows on transceiver and reflector side can be supplied.
