Completely Self-Contained - Selectable Particle Sizes
The GT-321 is completely self-contained with is 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, or 5.0 microns.
Fast Sampling
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. This 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.
Can be used with both 50 Hz and 60 Hz and 110 V or 220 V with local adapter.
