HPC 600 Airborne Particle Counter


The HPC600 handheld laser particle counter is the latest innovation in the demanding application of airborne particle counting. It is useful in counting particles in ultra-clean environment by its single particle counting ability. The instrument consists of a handheld set with a main base unit that allows users to conduct the sampling with a handheld set while easily expanding to multiple functionalities with a base unit. These extended functions include data downloading, data real-time printing, software upgrading, battery charging, and remote sampling. In addition to USB and RS232 interfaces, the RJ45 interface allows users to conduct the remote sampling away from the sampling location.

The HPC600 is the world’s first hybrid handheld optical particle counter. The instrument is a breakthrough of a new generation of particle counters that combines the traditional handheld instruments with functionalities of portable instruments. It is in compliance with the international standards (JIS B 9925:1997 and ISO14644-1) and supports both metric and English systems. All of its key components are made in the USA, Germany and Japan. It features high sensitivity, multiple functional capabilities, ease of use and reliability for extremely sensitive environmental measurement and advanced applications.
