NEO Monitors LaserGas - Model II SP -Single Path Monitor for In-Situ Measurement in Stacks

LaserGas II SP is 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.
