Condensation Particle Counter Model 3772 is a compact, rugged, and full-featured instrument that detects airborne particles down to 10 nm at an aerosol flow rate of 1.0 L/min, over a concentration range from 0 to 104 particles/cm3. It is ideally suited for applications that do not require measurement of high concentrations. The successor to our Model 3010, this value-priced CPC offers features found on our top-of-the-line CPCs. Like a front-panel display, anti-spill design, water-removal capability, built-in data logging and storage with removable memory card, and USB and Ethernet ports. Plus, the 3772 has built-in Scanning Mobility Particle Sizer™ (SMPS™) spectrometer compatibility, and it includes our Aerosol Instrument Manager™ software. It requires an external vacuum pump, available separately.
