PARTICLE COUNTER MODEL GT 521 - METONE

DUAL CHANNEL MADE IN USA

Big Performance, Small Size
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.

Dual Programmable Particle Channels
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.

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, Excel 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.
