Full-featured, portable, battery-operated, the GT-521 delivers the functionality of a bench unit with the ease and convenience of a handheld. This laser particle counter can either datalog counts continuously or send them right to a network.



Features


Two Programmable Channels
Duo programmable particles channels that each have a range of 0.3 to 5.0 microns. Each of these show differential or cumulative particle counts in real time with selectable count units.


Simple & Powerful Menu-Driven Command Set
A touch of a button will set sample times, alarms, particle sizes, and general set-up parameters like date and time and communications settings. Remote operation through RS-232 or RS-485 communication ports will allow for expansive control, including all front-panel operations.


Flexible Data Interfaces
Up to 4,000 records may be stored for Excel®-formatted output, printer output, or network data-logging through the accompanying single computer software, GT-Comm.
