PARTICLE COUNTER MODEL GT-521
Made in Met One - USA

Dual Programmable Particle Channels.

Two programmable particle channels with a range of 0.3 ï ¿ ½ 5.0 microns each show differential or cumulative particle counts in real time, with selectable count units.

Simple and Powerful Menu-Driven Command Set
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.

Flexible Data Interfaces
Stores up to 4, 000 records for printer output, Excelï ¿ ½ formatted output, or networked datalogging via the included single computer software ( GT-Comm) .

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.
