Self contained with selectable particle sizes
The Met One GT-321 is totally self contained and has an internal battery, sample pump, and is easily programmable which allows you to pick the desired particle size from 5 different sizes of 5.0, 2.0, 1.0, 0..5, or 0.3 microns.
Quick Sampling
Other particle counters may take up to 1 minute to produce a result, but the Met One GT-321 delivers volumetric concentration readings in around 6 seconds! This results in quick facilitatation of site particle trending, tracing particle sources, and multi site sampling.
Easy operation
Only 2 buttons on the front panel control the sample cycle size and channels. The power switch is side mounted which allows for easy thumb operation.
AC or Battery Power
The battery pack is self contained and provides power to the unit for 8 hrs. typical intermittent operation, & for a maximum of 5 hrs. continuous use. The AC adapter supplies the counter even while the battery pack has no charge, & recharges the drained battery in 16 hours when shut off.
