Portable airborne particle counter LPPC-B11 is an eight channel unit with higher flow rates that can confirm the class of a clean room. It has a provision of simultaneously counting particles in eight different size ranges with real time monitoring. It features a user-defined particle count limit thus offering end user flexibility. The particle count data can be conveniently viewed on screen, downloaded or printed directly using the built-in printer.
