The GT-526 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.

Six Particle Channels Displayed
Six preset particle channels ( 0.3, 0.5, 0.7, 1.0, 2.0, 5.0) show cumulative counts in real time, with selectable count units.

Menu-Driven Command Set for Out of the Box Operation
A simple touch of a button sets sample time, and basic setup parameters such as date/ time and communications settings. Remote operation via RS– 232 or RS– 485 communications port allows extensive control, including all front-panel operations.

Flexible Data Interfaces
Stores up to 8, 000 records for printer output, Excel® formatted output, or networked datalogging via the included single computer software ( Comet) .

Temperature and Relative Humidity Option
A plug– and– play option that immediately adds ambient temperature and relative humidity capabilities to the displayed and logged data.
