GT321 Datasheet, PDF (1/2 Pages) List of Unclassifed Manufacturers – Counts individual particles using scattered laser light

GT-321 Handheld
Particle Counter
The reliability you demand at
a price you won’t believe!
Small Size—Big Performance
The handheld GT-321 is a portable particle counter that
counts particles down to 0.3 microns—giving you portability
and reliability at the lowest price in the industry.
Completely Self-Contained—Selectable
Particle Sizes
Don’t let the size fool you—the GT-321 is completely self-
contained with its own internal battery and sample pump,
and is programmable, allowing you to choose your particle
size of interest from five sizes: 0.3, 0.5, 1.0, 2.0, or 5.0
microns.
Fast Sampling
Unlike other counters that can take up to a minute to
deliver results, the GT-321 starts delivering volumetric
concentration results in about 6 seconds! This facilitates
quick multi-site sampling, tracing particle sources and
site particle trending.
Simple Operation
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
The self-contained battery pack powers the unit for 8
hours of typical intermittent operation, and for up to 5
hours of continuous use. The included AC adapter
operates the counter, even when the battery pack is
discharged, and recharges the depleted battery
overnight (16 hours) when turned off.
