QAL181 MultiController Type
Max. 16pcs of sensors can be connected to a controller.
Suitable for emission gas measurement at big boiler or big kiln.
Long sensor (Whole length 1557mm) is available.
Self diagnosis function on the transmission surface of the sensor is available.
Operating Principles
Laser light is irradiated on dust particles, and the scattered light (forward light scattering method) is collected and scattered by the mirror, and then detected through the quartz rod. As forward-scattered light from which the largest scattering intensity can be obtained is collected with an efficient collection mirror and detected through the quartz rod without transmission loss, the monitor can make stable detections with less influence of noise.
