HAL-HPC300 Handheld Laser Particle Counters measures particles suspended in the air in real time with applications such as microelectronics, fine mechanics, optics, pharmaceutical, medical device, food processing, and aerospace. Because of its low-cost affordability, it is also widely used for indoor/outdoor air quality (IAQ) application. The basic operating principle of the HAL-HPC300 is that pulse signals generated from laser light scattering off aerosol particles are processed and counted, based on digital signal processing.
HAL-HPC600 6-channel handheld laser particle counter is the world's first of its kind hybrid handheld optical particle counter. The instrument is a truly breakthrough of new generation of particle counters that combines the traditional handheld instruments with functionalities of portable instruments for ultra-clean environment and indoor air quality applications.
