804 Handheld Particle Counter

Model 804 Handheld Particle Counter

Met One Instruments’ 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 very competitive pricing.

The 804 is simple to operate, using only two front-panel buttons and scroll wheel to control a user friendly, menu driven platform for easy configuration. Unlike other counters that can take up to a minute to deliver results, the 804 incorporates user selectable sampling times up to 1 minute and displays counts in as little as 3 seconds. The unit will take single or continuous samples. A self-contained battery pack powers the unit for 30 hours of typical intermittent operation, and up to 8 hours of continuous use.
