The Setra Systems 3301 & 3501 Series Particle Counter measures 0.3 μm to 25.0 μm through a long life laser diode and a flow rate of 0.1 CFM (2.83 LPM) with external vacuum source (by others) that pulls greater than >15” of Hg.

Easy to configure and with user configurable alarm light, this stainless-steel particle counter monitors 4 user-selectable size channels to allow for continuous monitoring of particulates in your critical environment.

Product Description

The 3301 and 3501 particle counters provide a range of particle size measurement from 0.3 or 0.5 to 25.0 μm at a flow rate of 0.1 CFM (2.83 LPM). These sensors allow for efficient particle counting with specifications that exceed the ISO 21501-4 and JIS B9921 calibration standards.

These sensors have 4 fixed particle size channels and are equipped with an integral critical orifice and flow sensor to provide a stable flow rate from an external vacuum source. Integration into a building automation or facility monitoring system is easy via isolated RS-485 Modbus communication.
