1.Light Transmittance Meter measurement principle
Light Transmittance Meter is used to measure the light transmittance (or light opacity) and dust concentration of the flue and provide accurate measurement results.The detection light crosses the flue, and is a single optical path measurement system, consisting of two parts: a transmitter and a receiver.A high-brightness LED light source is installed in the transmitter.It emits the light beam through the diffuser and passes through the flue, projected onto the focus lens in the receiver and is focused on the measurement detector; the other part is directly focused on the reference detector.By calculating the ratio of signal intensity obtained on the two detectors, the light transmittance or light opacity value can be obtained, thereby obtaining the light transmittance (or light opacity) and the dust concentration value.
2.Main features of Light Transmittance Meter
