Environmental Protection Agency has concluded that the air quality indoors can be up to 10 times worse than the air quality outdoors – even in the most industrialized cities. Yet, with this knowledge, it is hard to know whether or not you need to be concerned. How clean is the air in my home? In my office? This consumer air quality monitor is a breakthrough product that can accurately answer these questions and determine the indoor air quality wherever you need it.
Laser particle counters are sophisticated monitors used for the quick and accurate measurement of airborne particle concentrations. Traditional units are extremely high priced and are often used in hospitals, laboratories and clean room facilities – where clean air is critical. This innovative air quality monitor uses the same laser technology as the traditional units to give you the same accurate readings. However, this monitor has been redesigned to expressly meet the needs of home users – at an affordable price.
As air is cycled through the unit, both small and large particles are counted and displayed. Small particles counted include: fine dust, bacteria, mold, smoke, and smog. Large particles include: coarse dust, pollens, larger bacteria, plant spores, pet dander and dust mite feces. Anyone with allergies or asthma can use this information to specifically monitor their trouble areas. Someone with an allergy to pollen, for example, will be especially interested in their air’s large particle count.
The PC Interface Option has all the features of the standard DC1100 PRO, but also allows you to download the air quality data to a PC for graphing and analysis. A 9-pin serial cable (not included) links the DC1100 to your PC or laptop to transfer the data as it samples. To use this feature, you must connect a 9-pin serial cable from the unit to a COM port on your PC. If your PC lacks any COM ports, you’ll need to purchase a COM Port to USB adapter to use with the cable. You can then use any terminal program on the PC to communicate with the DC1100. Not all operating systems come with terminal programs. If yours does not, a terminal program must be purchased separately. Serial cables are available at most office supply stores, and terminal programs are easy to download. More detailed information and instructions are provided in the Owner’s Manual.
NOTE - Any software that comes with the cable must be installed before using.
DC1100 Pro has all the features of the standard DC1100 but with increased sensitivity - detecting particles down to 0.5 microns in size. The large particle size range is calibrated to 2.5 microns and above. The increased sensitivity (0.5 microns) makes this monitor perfect for those with more severe allergies who want to ensure that the air is clean of even very small particles. It is a great tool for helping to monitor and track how well your air purifier is cleaning your air.
The unit is small and lightweight, allowing you to easily test any area of your home. Take it anywhere you spend large portions of your day indoors. Use the information to take action to protect you and your family and give you peace of mind knowing that the air you breathe is safe and healthy.

I purchased the DC1100 Pro model because I needed something to help me to test small particles in the air .I search from the net to know this device can detect the particles less than 0.5 microns. It's very useful to detect the health air quality for me.
I just got an air purifier to clean the air in my bedroom,but the sensor of the purifier doesn't so sensitive to the bad air condition. So I need some reliable data to set the purifier's speed to purify the air. When I got the device I can easily know the air quality indoor and outdoor,so I can open the window for fresh air or not.
It can record the data within an hour,that was very helpful to calculate the air purifier purification efficiency,so I can calculate how much the air purifier effect I need to buy next time. Also I use it to record all the data during my sleep. When I was asleep, I turn the air purifier to the lowest speed to reduce the noise,using the device I can easily to know the air quality during the whole night, after that I assured use the air purifier all the night.
DC1100 Pro is very useful to monitor the indoor pollution, but without DC power it can't use to test the air quality in my car, so I got a mobile power to use it everywhere. BTW the 1700 version is a bit expensive, or I may choose it instead of DC1100 Pro.
In short, DC1100 Pro is the most cost-effective equipment for individual users.

This was a big disappointment.

Comments about Dylos DC1100 PRO Laser Particle Counter:
I use the unit to monitor PM2.5 for both indoor and outdoor. The result matches the official published data pretty well. When the reading is getting high in the room, I will turn on the air purifier.
Overall operation is easy. However, you can only review the histry recorded data backforwards, can't review the recorded data forwards.

Comments about Dylos DC1100 PRO Laser Particle Counter:
this is a must have if you really want to know how good your air quality is and how good your purifier is working and when you need to change your filter,well worth the price and shows you do not have to spend the big bucks to get a good filter,bottom line is what comes out and air flow
Comments about Dylos DC1100 PRO Laser Particle Counter:
Really a must if you are interested in knowing how clean your air is or how well your air cleaner is working. Of course I can't really tell how accurate it is but the numbers do seem to make sense based on the situation I put the sensor in.

Comments about Dylos DC1100 PRO Laser Particle Counter:
I bought this particle counter to test the air coming out of our air filters and it works well. It outputs numbers that give you an idea of how polluted the air actually is. I tested the room air, the air coming out of different filter units, and the outside air. Interesting fact: The outside air is much cleaner than any inside air even after it is filtered to Hepa level (at least in upstate NY).
Comments about Dylos DC1100 PRO Laser Particle Counter:
After viewing this unit being used by many manufactures of air cleaners, it was obvious that if I wanted to have any idea of how well my air cleaners were working, this was the way to go. The unit is VERY easy to use and works perfectly. No problem recommending it to anyone.
Comments about Dylos DC1100 PRO Laser Particle Counter:
Works exactly as advertised and fair price.
