Particle Monitor Hand-Held Monitor

This hand-held instrument is designed to quickly monitor particle size and concentration. The Model GT-321 particle monitor is a portable, battery-operated instrument, which measures particle sizes of 0.3 µm and above at concentration ranges as high as 3,000,000 particles/ft3. The instrument is ideal for clean room monitoring, ventilation system testing, filter testing, facility monitoring, process measurements, emissions monitoring, and other in-situ particle monitoring applications.

Extremely easy-to-use, the microprocessor-controlled GT-321 displays and updates particle size and concentration data at six second intervals, and provides a final measurement after 60 seconds. Results are displayed on a large LCD readout. Operation is as simple as selecting one of the five available particle size ranges and pressing the start button. The GT-321 operates from an internal, rechargeable battery pack, which provides up to eight hours of intermittent monitoring on a single 8-hour charge. The unit measures 6 x 3.5 x 2.5 inches and weighs approximately 1½ pounds.
