ONETEST-041 Is a multi-channel particle counter based on the principle of laser scattering, which can accurately measure 6 kinds of particle sizes including 0.3μm, 0.5μm, 1μm, 3μm, 5μm and 10μm.
Large screen display, three-button operation, simple and efficient operation, in a variety of scenarios can achieve rapid detection. Built-in high-performance lithium battery can provide the equipment to run continuously for more than 6 hours, at the same time built-in 512M storage, theoretical storage of no less than 7,000,000 data. Support USB communication, monitoring data can be viewed real-time data on the screen, or can be exported to the computer through Type-C port to view and analyze all data.
ONETEST-041 Has a higher measurement accuracy and particle size resolution, has a stronger ability to resist the effects of humidity. ONETEST041 Particle counter adopts industrial grade laser and photosensitive components, combined with the latest generation of light scattering particle monitoring technology, carefully tuned optical and gas path structure, as well as a new generation of high frequency weak signal processing circuit and high precision particle identification algorithm, more accurately measure the concentration of various environmental particles with cleanliness requirements.

Working principle
Using the single particle laser scattering principle, through the precise optical design and the hydrodynamic principle, the particles in the sampled air pass through the beam in turn to produce weak scattered light, collecting the scattered light and project onto the high sensitive and high bandwidth photodetector. The signal intensity of each particle is identified and analyzed by the particle size of each particle by conversion and aerodynamic calibration.
