Handheld 3886 and 3887 Optical Particle Counters (OPCs) simultaneously monitor particle size channels to provide particle concentration measurements displayed on a large four-line LCD. A built-in flow sensor enables highly accurate measurement of particle concentration for clothing and carpet fibres, mould spores, dust mites, asbestos fibres, skin cells, and other particles in the measuring range. 
 
Optional probes for relative humidity/temperature and air velocity may be added to the flexible 5-channel 3886 model for simultaneous monitoring of these important indoor air parameters. Compact and lightweight, these particle counters are easy to hold and the integral keypad simple to use. Battery operation allows monitoring in remote locations. Data can be downloaded to a PC.
