An essential tool for HVAC and IAQ professionals, the Fluke 985 can be used to easily determine particle concentration and is suited for measuring filter efficiency, monitoring industrial cleanrooms and locating particle sources.
Featuring internal 10000 record memory, the Fluke 985 can store a huge amount of measurement data captured using its six channels. This information can be viewd as standard measurements, or alternatively can be viewed in a tabular or trend graph. By using a USB memory stick or cable this data can then be sent to PC and interacted with using a standard Excel software package.
The 985 can be fully configured to the user's specifications. With just a few button presses, makes adjustments to sample methods and set your own alarm thresholds for raw count, per cubic feet, cubic meter or in litres.
This products meets ISO 21501, JIS B921 and CE standards.
