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.


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.

Details

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.
