The REED R9930 is a handheld air particle counter that reports up to six particle size channels down to 0.3 microns, paired with a built-in still/video camera so technicians can visually document the exact spot being sampled. A 2.8 in color TFT screen shows live readings alongside ambient temperature, humidity, dew point and wet-bulb data, while captured images, video and logged counts can be stored on a removable microSD card or in onboard memory. It ships with PC software, a zero-count filter, rechargeable battery, SD card and a hard carrying case, making it well suited to cleanroom and indoor air-quality verification work.
