2 Channel Handheld Particle Counter GT-521

2 Channel Handheld Particle Counter GT-521 Large

The GT-521 is a full-featured, battery-operated, portable laser particle counter that provides the functionality of a bench unit with the convenience of a handheld! It can datalog particle counts continuously or send them to a network.

Two programmable particle channels with a range of 0.3 – 5.0 microns each show differential
or cumulative particle counts in real time, with selectable count units.

A simple touch of a button sets particle sizes, sample time, alarm settings, and basic setup
parameters such as date/time and communications settings. Remote operation via RS-232 or RS-485 communications ports allows extensive control, including all front-panel operations.
Stores up to 4,000 records for printer output, Excel® formatted output, or networked datalogging via the included single computer software (GT-Comm).
A plug-and-play option that immediately adds ambient temperature and relative humidity
capabilities to the displayed and logged data.
