Handheld Optical Particle Counter Dust Detector USB Port Air Quality Analyzer

Description

Handheld Optical Particle Counter Dust Detector USB Port Air Quality Analyzer
Instruction:
The Model CW-HPC300(A) handheld optical particle counter utilizes the laser technology for single particle detection. The scattering of light from the particles in the sampling air steam is converted into electrical pulses, which is then measured and calculated as a particle size.  The CW-HPC300(A) consists of a handheld set with a main base unit that allows users to conduct the sampling around with a handheld set while easily expanding to multiple functionalities with a base unit.   These extended functions include data downloading, data real-time printing, software upgrading, and batterycharging, etc.
The Particle count data is displayed as Concentration mode(Counts/Liter or
Counts/Cubic foot, Counts/Cubic Meter).  The Model CW-HPC300(A) can also include a digital temperature and relative humidity probe, back lit interface and is capable of
storing 3,000 sample records.   lt is in compliance with the intemational standards(JIS B9925:1997 andlS014644-1) and support both metric and English systems.
