Accurate - Reliable – Affordable
Seven Sizes: 0.3, 0.5, 0.7, 1.0, 2.5, 5.0 or 10.0 microns
Met One's 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 realiability at a low price.
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 samplint 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.
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.
Stores up to 2500 records for output, Excel formatted ouput via included single computer software. USB interface provides quick data download and field firmware upgrades.
