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. The settings of measurement parameters as well as results displayed in total counts, number concentration or/and mass concentration (new feature for IAQ application) are all controlled and realized by an internal microprocessor (MCU).

The HPC300 simultaneously measures three channel sizes that are configurable by a user. The data recorded in the embedded flash memory can be downloaded with supplied software through either a USB or RS232 interface.

The HAL-HPC300 was designed in the USA and is in compliance with the international standards (JIS B 9925:1997 and ISO14644-1) and has CE certification. The HPC300 instrument is very unique compared to other manufacturers in the market; it features high sensitivity, multiple functional capabilities, and is slim, lightweight and very user friendly.
