【OPTICAL SENSOR】Temtop’s laser light scatter technology offers uniquely broad particle size detection. The all-new PMD331 has an ultra-low detection limit, down to 0.1-micron particle size with a unit detection range of 0 to 3,000,000 CF. The continuous flow optical sensor is coupled with purge air to ensure accurate measurements in a wide range of environments without performance degradation. 【ADJUSTABLE INTERVAL TIME】User-adjustable sample times include 3-60 second intervals which facilitates environmental profiling in various applications. Ideal for both long-term sampling, a large display offers ease in viewing from across the room.Supports RS232 communication interface. 【USER-FRIENDLY】7-buttons enable easy access to menu-driven setup and sampling. The PMD331 offers selectable sample modes of TC/CF/L 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 2,000,000 sample records which a
