P311 Laser Particle Counter
The P311 has a concentration limit of 4,000,000 particles / ft; the highest concentration limit available on the market. Typically particle counters are designed for very clean environments such as clean-rooms. So when customers use most particle counters inan Indoor environment, they max out concentration levels quickly. (Majority of products peak concentration levels are 2,000,000 particles / ft). The P311 can be used in clean-room as well as typical air indoor environments. This makes it an excellent unit for insulators, asbestos abatement and IAQ. Note: the P311 is a particle counter and not a particle identifier.
Data can be checked on the unit's display and/or easily downloaded to your PC via USB cable and saved as a CSV file which is transferable to Excel. P311 is accurate, dependable, user friendly, compact and light weight.
The P311 has a very large color display that shows cumulative and differential particle counts of 3 particle sizes simultaneously. The middle channel is also selectable by the user.
