For mobile measurements. For determining the quantity of dirt particles in the air caused, forexample, by combustion, manufacturing, energy production, vehicle engine emissions and the construction industry. Three different methods of counting. Cumulative: adding up the number of particles per measuring channel starting with the largest channel; differential: absolute number of particles per channel; concentration: average number of items per channel (=particle density) Measurement duration can be adjusted or measurement via start/stop button Also sensors for continuous measurement of air temperature, dew point temperature, wet-bulb temperature and relative air humidity Automatic data storage once the measuring process is complete Built-in camera on the back to link the measurement data to image/video material Automatic shutdown can be adjusted (3 to 60 minutes) and deactivated Particle counter PCE-PCO series PCE-PCO 1 For measuring the particle concentration. Delivery incl. zero filter, battery, charger, USB cable, stand and hardshell case.
