Filter performance

The CLJ-H303 model is reliable and easy-to-use machine; it’s handheld, ergonomically designed and lightweight

The Model CLJ-H303 counts airborne particles in six different size ranges simultaneously. Count data is displayed on screen (320×240 pixels, high resolution) as total number of particles (cumulative count). Data can be easily downloaded to computer, or print out by an optional printer.

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 to computer. The large LCD display lets you see the data easily and err-free.
