Met One’s 804 handheld particle counter is a 4 channel portable particle counter that counts particles 0.3 microns to 10.0 microns – giving you portability and reliability at the lowest price in the industry. Don’t let the size fool you–this unit is completely self-contained with its own internal battery and sample pump, and is programmable, allowing you to choose your particle sizes of interest from seven sizes: 0.3, 0.5, 0.7, 1.0, 2.5, 5.0 or 10.0 microns.
Met One Instruments’ handheld GT-321 is a portable particle counter that counts particles down to 0.3 microns—giving you portability and reliability at very competitive prices. Don’t let the size fool you—the GT-321 is completely self- contained with its own internal battery and sample pump. The 321 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.
Our GT-521S is a full-featured, battery-operated, portable particle counter that provides the functionality of a bench unit with the convenience of a handheld. This powerful device supports cumulative or differential counts, standard concentrations, total counts and count alarms. It can log particle counts continuously locally as well as send them to a network.
The GT-526S is a full-featured, six-channel, battery-operated, portable particle counter that provides the functionality of a bench unit with the convenience of a handheld. The six-channels can be configured to factory calibrated standard sizes or user defined custom sizes. The 526S has two alarm limits and several communications options. It can store up to 8,000 samples including temperature and relative humidity; if the optional sensor is connected. Sample history can be viewed on the unit’s display or printed if the optional printer is connected.
The BT-610 is a portable airborne particle counter with a small stable footprint. This allows you to move the 610 around yet operate it without having to hold it. The 610 has six selectable size channels, a built-in printer, and is housed in a portable stainless-steel case. Flow rate is 0.1 cfm (2.83 lpm) and is maintained with volumetric flow control for improved accuracy.
The BT-620 includes all of the features of the BT-610 with the exception of the flow rate. The 620 flow rate is 1.0 cfm (28.3 lpm) and is maintained with volumetric flow control for improved accuracy. Like the 610, the 620 data is easily viewed on its display from distances exceeding 3 meters.
