This means it will count accurately even in close proximity to sources of interference, such as industrial machinery, fluorescent lights, and high voltage power supplies found in some air purifiers. The DC1700-PM is shielded against Electro-Magnetic Interference. The user can set the time and date easily from the front panel of the DC1700-PM. The DC1700-PM has a real time clock which is used to time stamp the data in stored internal memory. The internal data can be downloaded as either particle concentration or mass concentration. This means that the DC1700-PM can be left in a location sampling and then brought to a PC where the data can then be downloaded and loaded into Excel or other spreadsheet programs for analysis. The DC1700-PM has a large internal memory which can store up to a week's worth of time-stamped data recorded every minute (over 10,000 samples). In addition to the DylosLogger the DC1700-PM data can be downloaded by any terminal program or custom software.ĭisplay and Graph in PM2.5/PM10 mass concentration and in >0.5micron/2.5micron particle concentration A 9pin serial cable or USB-to-COM Port Adapter (not included) is needed to link the DC1700-PM to your PC or laptop. This data is output in a format ready to load into a spreadsheet program such as Excel for further graphing or analysis. The DC1700-PM includes the DylosLogger 3.0 program which can download the stored data along with the time it was taken. The DC1700-PM can also be operated off AC using the included wall adapter The DC1700-PM has an internal battery which provides up to 6 hours of continuous use (one or more days of typical usage) on a single charge. The DC1700-PM has a menu which allows the user to enter a correction factor based on local readings from the nearest government monitoring station. Particles in different areas will have different characteristics which can produce errors in the PM2.5 readings of light scattering monitors. Like earlier models it has multiple modes including minute, hour, day and monitor to evaluate your air quality, but also includes the following features: The LCD also includes a dynamic bar graph showing instantaneous particle activity. The user can easily switch between displaying mass (PM2.5/PM10) or concentration (>0.5 micron/>2.5 micron). It features technology and engineering that allow monitoring of indoor and outdoor air quality. The DC1700-PM can display the particle readings as either particle concentration (>0.5um,>2.5um) or as mass concentration in PM2.5/PM10 (ug/m3) for direct comparison to the EPA. The DC1700-PM is an improved version of the DC1700 battery operated air quality monitor. A true Laser Particle Counter with 2 size ranges (>0.5 & >2.5 microns) - small (bacteria, mold, etc) large (pollen, etc.)
