1. Reliable and easy-to-use machine. 2. Portable and battery(Direct current) operated.

The CLJ-BII(J) 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(J) 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.   Features:1. 0.1cfm (2.83lpm) flow rate;2. 2 counting modes;3. Six particle-size channels (0.3, 0.5, 1.0, 3.0, 5.0, 10µm);4.
