Met One Instruments – Single Channel Particle Counter – GT-321

The GT-321 contains a laser diode based sensor, NiCd battery pack, vacuum pump,microprocessor electronics, LCD display and user input keys all in one small package.The accuracy of the GT-321 is certified according to ASTM and JIS standards andcomparable to larger more expensive bench top particle counters. The fast 6-secondresponse of the GT-321 makes it especially useful for troubleshooting contaminationproblems and tracing contamination leaks to the source.

Key Features

• 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.
