2000 Series Remote Airborne Particle Counters
Models 2501-1 and 2501-4
0.5 – 5 µm @ 0.1 CFM
Firstly, the 2501-1 Remote Particle Counter measures 0.5 μm and 5.0 μm with a flow rate of 0.1 CFM (2.83 LPM). Integration is easy into a real-time monitoring or building management system via Modbus RTU or ASCII.
On the other hand, the 2501-4 Remote Particle Counter measures 0.5 μm, 0.7 μm, 1.0 μm & 5.0 μm with a flow rate of 0.1 CFM (2.83 LPM). Integration is easy into a real-time monitoring or building management system via Modbus RTU or ASCII.
Most importantly, the 2000 Series are the smallest remote particle counters on the market and has easy mounting options. The units comply with ISO 21501-4 and include a 2 year limited warranty.
