Features :

• Measurement after the purification efficiency of paragraph purification machine automatically calculates the number of dust particles out of gas  in accordance with the current measurement vent.
• Testing of high precision, stable performance, strong versatility, easy operation, reach and exceed the performance of similar products

Laser light scattered by dust particles on the optical sensor outputs a pulse signal for digital signal
processing, measurement parameter setting, the results show a button, time, date, etc. by the
control and implementation of the built-in microcomputer (MCU).
