Portable airborne particle counter LPPC-A21 is a six channel microcomputer controlled unit. It has a provision of simultaneously counting particles in six different size ranges with real time monitoring. Equipped with built-in thermal sensitive printer for direct printing of pre-recorded and current data for end user convenience. The particle count data can be conveniently viewed, downloaded or printed directly using the built-in printer featuring multiple print mode.
