Handheld Laser Particle Counter Model 3886 "GEO-α"

Features Simultaneous measurements/monitor of particle concentration, relative humidity, temperature and air velocity in a single instrument. 5 particle size channels(0.3,0.5,1.0,3.0 and 5.0 µm) Built-in flow sensor enables highly accurate measurement of particle concentration(0.1CFM±10%) Efficient data storage and logging capability.(500 data can be stored internally) Compact and light weight can be used as a multi-point monitor by cascade connection Remote control by external computer
