The YESDUST is a general purpose particulate sensor for use with a YES multi-channel monitor (e.g. YESAIR and YES Plus LGA).  It operates from an internal rechargeable nickel hydride battery pack and connects to the auxiliary port of the YES multi-channel monitor with the supplied interface cable. The measured readings are displayed as another sensor on the LCD display of the YES multi-channel monitor, and are also data logged to the YES multi-channel monitor internal flash card, if utilized.

YESDUST counts particulates between 1 and 10 microns in size. It has been designed for use as a general purpose indication of a particulate problem and should not be considered for applications requiring high accuracy such as “clean rooms”.
