Single Path Monitors are designed for in-situ measurement in stacks, ducts, or reactors with typical path lengths in the range 0.5 to 20 meters. By-pass and extractive configurations are also possible.

The monitors’ compact design comprises the transmitter unit with laser module; collimating optics, and main electronics and the receiver unit with focusing lens, photo detector and receiver electronics.

The LaserGas^TMII SP Monitor utilizes a transmitter / receiver configuration (mounted diametrically opposite each other) to measure the average gas concentration along the optical line-of-sight.
