Bettersize C400 optical particle counter Introduction
BettersizeC400 optical particle counter is a double light path particle counter with international advanced level. The BettersizeC400 optical particle counter uses the measurement principle of the combination of photoresistance and angular scattering. The two methods are combined with each other and confirmed each other, which expands the measuring range of the instrument and also ensures the accuracy of the measurement. The system includes a sampling system and a measurement system. The samples pass through the measurement area one by one through the sampling system. After the laser is irradiated to the sample, the sample is blocked by light and the fluctuation of the scattered energy. Then the analog signal is detected by the optical sensor, and the analog signal is collected and converted by high-speed AD. The transmission method transmits the digital signal to the computer, and the particle size, cleanliness level and particle size distribution result in the sample can be obtained by analyzing the signal by special particle testing software. Features
Adopting the measuring principle of the combination of photoresistance and angular scattering, the two methods are combined with each other and confirmed each other, which expands the measuring range of the instrument and ensures the accuracy of the measurement.
One-step operation and fast detection (combining automatic functions such as automatic sampling, automatic detection, data processing, and automatic cleaning).
It can measure both the particle size distribution and the number of particles.
High-speed signal acquisition, analog signal conversion and restoration technology, the communication between the processor unit (ARM) and the PC uses the USB2.0 high-speed mode, which can reach 40Mbyte per second, which can effectively ensure the real-time, continuity and accuracy of the signal.
