Six programmable particle sizes. Operator can set each size from 0.3 to 10 microns.
Count Alarm Limits
Two programmable count alarm limits. Alarms are indicated by an audible beep, displayed message and an alarm flag in the data file.
Data Storage
Store up to 8,000 sample events. Sample history events can be viewed, printed on the optional printer and download to a computer using Comet software or simple ASCII terminal commands.
Battery Powered
24 hours of typical (intermittent) operation and 10 hours of continuous operation. Recharge time is only 2.5 hours.
Temperature / Relative Humidity Option
A plug-and-play option that immediately adds ambient temperature and relative humidity capabilities to displayed and logged data.
GT-321 Single Channel Particle Counter
The reliability you demand at a price you won’t believe!
Small Size—Big Performance
The handheld GT-321 is a portable particle counter that counts particles down to 0.3 microns—giving you portability and reliability at the lowest price in the industry.
Completely Self-Contained—Selectable Particle Sizes
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.
Fast Sampling
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.
Simple Operation
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.
Off-the-Shelf Delivery
Units are available for same-day or next-day shipping!
GT-521S Two Channel Particle Counter
Bench unit performance in the palm of your hand.
Big Performance, Small Size
The GT-521S is a full-featured, battery-operated, portable laser particle counter that provides the functionality of a bench unit with the convenience of a handheld! It can datalog particle counts continuously or send them to a network.
Dual Programmable Particle Channels
Two programmable particle channels with a range of 0.3 – 5.0 microns each show differential or cumulative particle counts in real time, with selectable count units.
Simple and Powerful Menu-Driven Command Set
A simple touch of a button sets particle sizes, sample time, alarm settings, and basic setup parameters such as date/time and communications settings. Remote operation via RS-232 or RS-485 communications ports allows extensive control, including all front-panel operations.
Flexible Data Interfaces
Stores up to 4,000 records for printer output, Excel® formatted output, or networked datalogging via the included single computer software (GT-Comm).
Temperature and Relative Humidity Option
A plug-and-play option that immediately adds ambient temperature and relative humidity capabilities to the displayed and logged data.
Aerocet-531S Mass Particle Counter/Dust Monitor
2-in-1 performance!
Particle Mass Profiler and Counter in a Single Handheld Unit
The Aerocet 531S is a small, handheld, battery operated, and completely portable unit. This unit provides particle counts or mass PM measurements as stored datalogged values, real-time networked data, or printed results.
Six Mass Ranges and Four Particle Sizes
Six important mass size ranges (PM1, PM2.5, PM4, PM7, PM10, and TSP) are displayed in mass mode as well as four popular cumulative particle sizes (> 0.5, 1.0, 5.0 and10.0 microns) in count mode.
Tailored Mass Conversion
The particle counts from eight size ranges are converted to mass using a proprietary algorithm for typical-density aerosols. Accommodation for special particulate with different densities is provided through user–programmable “K-factors."
Flexible Data Interfaces
The Aerocet 531S stores up to 6,257 records. These records can be viewed on the display, or transferred to a computer via USB or RS232. Our included Comet download utility makes file transfers easy. Data files can easily be imported into an Excel® formatted output.
Temperature and Relative Humidity Option
A plug-and-play option that immediately adds ambient temperature and relative humidity capabilities to the displayed and logged data.
804 Four Channel Handheld Particle Counter
Accurate – Affordable – Reliable
Small Size—Big Performance
The 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.
Completely Self-Contained—Selectable Particle Sizes
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.
Fast Sampling
Unlike other counters that can take up to a minute to deliver results, the 804 incorporates user selectable sampling time up to 1 minute and displays counts in as little as 3 seconds. The unit will take single or continuous samples.
Simple Operation
Only two front-panel buttons and scroll wheel provide a user friendly, menu driven platform that provides ease in configuration.
Battery or AC Powered
The self-contained battery pack powers the unit for 30 hours of typical intermittent operation, and for up to 8 hours of continuous use. The included AC charger / adapter operates the counter, even when the battery pack is discharged, and recharges the depleted battery in 2.5 hours.
Flexible Data Interfaces / USB Communication
Stores up to 2500 records for output, Excel formatted output via included single computer software. USB interface provides quick data download and field firmware upgrades.
