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 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. Off-the-Shelf Delivery Units are available for same-day or next-day shipping! Applications: Controlled Environments Indoor Air Quality Process Control HVAC Applications Filter Testing Laboratory Environments Manufacturing Environments Emission Sourcing Whatever your particular needs, the right choice is only natural.
