The wall mounted DC1100-PC connects directly to our Model SC80 wireless RS-232 transmitter in our logging and monitoring systems. A true particle counter monitor with 2 size ranges - small (bacteria, mold, etc) large (pollen, etc.).Sensitivity for small particulate is down to 1 micron and large particulate is above 5 microns.
The DC1100 Pro offers all of the features of the DC1100 but is capable of detecting particles down to 0.5 micron. The large particle size range is calibrated to 2.5 microns and above.
