Dylos Laser Particle Counter (DC1100)

The laser particle counter is incredibly easy to use. I just took it out of the box, plugged in the AC adapter, and it started giving measurements immediately without requiring time to acquire a sample. I did find that when moving it from room to room you need to give it some time to stabilize at the new value. Maybe it takes some time for the old air to be purged with new air. It gives appearances of being accurate. In a room with a HEPA filter it measured 50 small (all particles down to 1 micron) and 5 large (5 microns and above) particles per 0.01 cubic feet. In a room without a filter it measured 200 and 25. In a dusty room it measured 440 and 78. (I’m not sure about the units. A cleanroom website said that a typical office building has 500,000 to 1,000,000 particles per cubic foot. Is my bedroom really a class 5000 cleanroom?) There is a discrepancy between the manual and the website’s description. The manual says that “Small particles are all particles detected by the DC1100 down to its detection limit – approximately 1 micron.” while the website says that “small” equals 1 – 5 microns. When you start it up it reads continuously, but it saves readings on a minute to minute basis. By hitting the mode button you can access this data on a minute to minute, hour to hour, or day to day basis, with the reading being the average concentration over that minute, hour, or day. To save energy and wear and tear on the instrument, you can select the “monitor” mode, in which it only samples for one minute per hour.
