The CLJ-BII model is reliable and easy-to-use machine; it’s portable, six size channels, and a built-in printer— all in one compact instrument! The Model CLJ-BII counts airborne particles in six different size ranges simultaneously. Count data is displayed on the front-panel as total number of particles (cumulative count). The printout shows cumulative count data for each size range. Now it is easy to carry a particle counter right to the point of interest and obtain accurate results–results you can immediately print or store in buffer . The bright LED display lets you see the data easily and err-free. |

Principle:
The particle counter uses an laser light source and collection optics for particle detection. Particles scatter light from the light source in the direction of the collection optics. The collection optics focuses the light on a photoelectric cell that converts the bursts of light into electrical pulses. The pulse height is a measure of particle size. Pulses are counted and their intensity is measured for particle sizing. Results are displayed as particle count in the specified size channel.
