| Compteur de particules |
| modèle GT - 521 |
| Bench unit performance in the palm of your hand. |
| Big Performance, Small Size |
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. |
| 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 |
Only two front-panel buttons control the size channels and sample cycle. The side-mounted power switch allows for convenient thumb operation. |
| Battery or AC Powered |
| 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. | |
| Applications: | |
| Controlled
Environments Indoor Air Quality Process Control HVAC Applications Filter Testing Compliance Testing Emission Sourcing Remote Sampling QA Programs |
Whatever your particular needs,
the right choice is only natural. |
