Digital Temperature and Relative Humidity Sensor Probe

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.
