Portable particle counter | MET ONE GT-521

The GT-521 is a complete, battery-operated portable particle counter that offers the functionality of a bench unit with the convenience of a handheld computer.
 
The GT-521 allows the user to select particle sizes with two programmable counting channels ranging from 0.3 to 10 microns, each displaying real-time differential or cumulative particle counts, with counting units selectable by 0.01 micron increments. The 521 has a simple and powerful menu-driven set of commands. One push of a button sets particle size, sampling time, alarm settings, and basic configuration settings such as date / time and communication settings. Remote operation via USB (cable supplied) or RS-232 / RS-485 (optional cable) allows extensive control, including all front panel operations. The GT-521 can store up to 8,000 sample events with output to printer, Excel or network data logging via the included software (Comet). Sample history can also be viewed on the local screen or downloaded to a computer using the supplied Comet software.
 
The GT-521 is battery powered with 24 hours of typical operation (intermittent) or 10 hours of continuous operation from a single charge. Charging time is approximately 2.5 hours. The GT-521 can also be equipped with a plug-and-play temperature / relative humidity option, which immediately adds ambient temperature and relative humidity capabilities to displayed and recorded data.
