The 804 hand-held 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.
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.
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. USB interface provides quick data download and field firmware upgrades.
