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, Inc.’s Model GT-324 particle counter is a full-featured handheld particle counter that provides the functionality of a bench unit in a portable package. A fully integrated RH/Temp sensor immediately provides data to your displayed and logged data. A convenient unit for compliance, the user interface is simple with the multifunction rotary dial. Comply with 21 CFR Part 11 using the password feature to prevent unauthorized changes to user settings. Unit is 21501-4 compliant capable. All new units include an NIST traceable certificate of calibration and the upgraded Particle View software package. Particle View now features additional reports, alarms, charts and conversions for improved data analysis. The 324 has seven selectable sizes; 0.3, 0.5, 0.7, 1.0, 2.5, 5.0 and 10.0 microns of which the operator can choose any 4 of the particle sizes of interest. The GT-324 is suitable for many applications, including but not limited to, Cleanroom Monitoring, Controlled Environments, Filter Testing, Compliance Testing, Process Control, Indoor Air Quality, HVAC Applications, QA Programs, etc.
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.
