Overview

The airborne particle counter is based on the principle of particle extinction, using a unique optical spatial low-pass filtering hardware technology, combined with diffraction correction algorithm patents, which can accurately measure the particle size distribution and number of micrometer sized airborne particles, covering the pain points of not being able to monitor large particles in the current instrument market.

Product Details

The existing photoresist particle counters have been widely used for monitoring airborne particles in clean rooms. However, due to limitations in optical path principles and sampling algorithms, the existing photoresist instruments cannot accurately sample and measure large particles in the air.

This instrument is based on the principle of particle extinction and uses optical spatial low-pass filtering hardware technology, combined with diffraction correction algorithm, to accurately measure the particle size distribution and number of micrometer sized airborne particles, covering the pain points of the current instrument market that cannot monitor large particles.

APC 610Airborne particle counterVs traditional photoresist particle counter

Truth Optics APC 610Airborne particle counter	Traditional photoresist particle testing method
Capable of measuring the true geometric particle size of particles	Can only measure the equivalent extinction particle size of particles
The measurement accuracy is not affected by the refractive index and absorption coefficient of the particles, and accurate measurement results can be obtained regardless of the material composition of the particles	Due to the influence of the refractive index and absorption coefficient of particulate materials, such as particles with lower absorption coefficients, the measurement results may be smaller; On the contrary, the measurement results will be biased towards larger values
High measurement accuracy, with a theoretical error of no more than 1% in particle size measurement	Accuracy not guaranteed
Can provide detailed granularity distribution data	Can only provide rough granularity segmented data
The measurement unit is designed to be separated from the drive unit and directly connected to the sampling bucket. The measurement unit can be placed in a small space for measurement, avoiding the impact of pipeline pollution on measurement accuracy	The sampling bucket can only be placed in the measurement space, and the sedimentation and contamination of particles in the pipeline directly affect the accuracy of the measurement results
The measuring chamber and sampling bucket inside the measuring unit are detachable for easy cleaning and replacement; And pipeline pollution has no impact on measurement	Difficulty in cleaning the measurement room and thoroughly cleaning the pipelines
