Y09-6H3 Laser Dust Particle Counter (handheld) is a portable device with built-in lithium battery and miniaturization. As the
particle count, the 0.3, 0.5 and 5.0 μ m3 channel particle data can be displayed in real time, and the cumulative particle number
of three channels can be displayed after a sampling period. The dust particle counter has built-in long-life laser diode, light
collection elliptical lens and unique optical system to provide concentration measurement range. The dust particle counter has
built-in 7.4V lithium-ion battery pack, vacuum pump, isokinetic sampling head, micro processing circuit and computer interface.
All information is displayed on the LCD screen.
