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.
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.
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.
Met One Instruments Inc. is one of the leaders in research, development and manufacture of meteorological instruments, particulate monitors, data loggers and environmental software. One of the oldest instrument manufacturer's in the United States, MOI continues to provide the leading edge in instrumentation, data logging, environmental software and monitoring systems worldwide.
The company began business in 1976 as Met One, Inc. The first of several high quality "Met Set" meteorological monitoring systems and a line of clean room monitoring instruments were introduced. Growth was brisk and the company quickly outgrew the facilities. In 1989 Met One Instruments, Inc. was formed to focus on the growing environmental market and the entire meteorological product line was transferred at that time.
The company has grown through careful planning, dedication to customer service and the ability to design and manufacture quality products. Additional growth has come about with company acquisition and joint venture partnerships
