The Apex Portable Particle Counter can store up to 3,000 records of particle count data from up to 4 particle channels and the configurable database can store up to 50 recipes for sampling and reports.


     The Apex Portable Secure Data Transfer allows all particle count data to be quickly and reliably transferred to a USB flash drive, Computer, Facility Monitoring System or Building Automation System. Apex Portable has a flexible data communication through the integrated RS-485 Modbus and USB flash drive interfaces.



Data Integrity

     Apex Portable was designed with an internal Self-Diagnostic technology that continuously monitors the health of the laser ensuring reliability of the particle count data. Apex Self-Diagnostics on the laser, flow rate and particle detector ensure that data being collected is operating within specified tolerances.

Data Availability
