Air Quality | 831 Four Channel Handheld Particle Counter

Small – Reliable – Affordable

Four Mass Ranges (PM1, PM2.5, PM4, PM10)
A mass monitor that simultaneously provides data of four important mass ranges in one minute.

Handheld Operation
Survey the environment with this extremely portable, size selective mass monitor. This small lightweight instrument is only 28 ounces and is the perfect survey tool for a wide range of applications.

Simple Operation
Only two front-panel buttons accompany the multifunction rotary scroll wheel to provide simple and efficient operation. Just press and rotate to scroll thru the menu driven platform.

Sample History
View sample history easily on the display or export data via the USB port using the included software. Unit stores up to 2500 sample events. USB interface provides quick data download and field firmware upgrades.

Battery Powered
24 hours of typical intermittent operation and up to 8 hours of continuous use. Recharge time is only 2.5 hours. The included AC charger / adapter operates the counter even when the batter pack is discharged.
