GT-321 Single Channel Particle Counter

Product SKU: GT-321

Quick Overview

The GT-321 is small and portable but it’s also chock-full of features, like the fact it’s a self-contained unit with an internal battery and sample pump, it delivers sampling at a high rate of speed, and is designed for ease of use – among other excellent features.


Small In Size – Big In Performance

The portable GT-321 particle counter counts particles down to 0.3 microns. One of the most economical, reliable handheld particle counters in the industry.

Self-Contained with Selectable Particle Sizes

The GT-321 may be small and portable but it’s also self-contained with an internal battery and sample pump. It’s also programmable; choose from five particle sizes: 0.3, 0.5, 1.0, 2.0, or 5.0 microns.

Speedy Sampling

Other counters may take up to a minute to produce results, but the GT-321 begins delivering volumetric concentration results in about six seconds, which lends itself to faster multi-site sampling, site particle trending, and tracing particle sources.

Uncomplicated Operation

Designed for ease of use with two front-panel buttons that control the sample cycle and size channels. Conveniently operate with the thumb thanks to a side-mounted power switch.

Battery- & AC-Powered

With a self-contained battery pack, your GT-321 is powered for eight hours of typical, intermittent use, and up to five hours of continuous use. An AC adapter is included, which operate the counter even when the battery pack is discharge. This adapter will recharge the depleted battery overnight (16 hours) while turned off.
