Aerocet 380 Portable Dust Monitor

The Aerocet 380 is a Nephelometer developed by Met One Instruments Powered by Acoem that offers real-time airborne TSP (total suspended particulate) concentration levels using the principle of forward-laser light scatter. This instrument is ideal for sampling in any indoor workplace or public place environment with optional separators to monitor PM1, PM2.5, or PM10.

Optical Sensor

Met One’s forward-laser light scatter technology offers uniquely broad particle size detection. The all-new Aerocet 380 has an ultra-low detection limit, down to 0.1-micron particle size and 1.0 µg/m3 particle sensitivity, with a unit detection range of 0 to 100,000 µg/m3. The continuous flow optical sensor is coupled with purge air to ensure accurate measurements in a wide range of environments without performance degradation.

Highly Portable

This sleek, aluminum, all-in-one desktop instrument provides continuous sampling with an AC adaptor or 8 hours with batteries that fully charge in less than 3 hours. The Aerocet 380’s user-friendly interface comes complete with download utility software easily accessed via Wifi.


User-adjustable sample times include 1-, 5-, 10-, 15-, 30-minute, and 1-hour intervals which facilitates environmental profiling in various applications. Ideal for both long-term or remote sampling, a large display offers ease in viewing from across the room.


Two buttons and a rotary dial enable easy access to menu-driven setup and sampling. The Aerocet 380 offers selectable sample modes of μg/m3 or mg/m3 and alphanumeric location IDs, giving the user the ability to identify a unique name to a location or sampling area. This dust monitor can store up to 15,000 sample records which are easily accessed on-screen or downloaded to a computer with the included utility software.
