Boulder Counter

With its 5.7-inch (14.47 cm) color touch screen, the BOULDER COUNTER is easy to configure and operate. It can store 3,000 records of particle count data from 6 channels and environmental data from up to 4 sensors (4-20 mA). All data can be quickly and reliably transferred to a computer or printed on its built-in thermal printer.

Demonstrating its versatility, the BOULDER COUNTER can be used as a portable instrument or integrated into a facility monitoring system.

Designed and built by Lighthouse Worldwide Solutions, a name you can trust.
