  CCW-101 - Clean Checker

Portable Dust Observation Device
Clean Checker visually evaluates airborne dust (pollutants)
such as house dust, pollen, smoke, asbestos, and other
airborne contaminants invisible to the naked eye.
You can visually observe air pollution in the work
environment, such as construction sites or
house dust that causes sick building syndrome.
← low dust level high dust level →

   Set Composition & Price

Using the inspection glass bottles, water pollution
can also be checked and visually observed.
You can compare and measure the water quality
of tap water, well water, river water, etc. that has
gone through a water purifier, or observe and
measure the dirt and plankton in the water
due to dust and pollen contamination.

1. Move the slider down
and open the air chanber.
Take in the air of the

** Table View
   1. Start an air-cleaner in the cigaret smoke filled laboratory.
   2. Using particle counter, measure air borne dust of 0.3μm / 0.5μm / 1μm at fixed time frame.
   3. Capture image via CCW101 lens at the same time and superimposed resulting value on the graph
     As a result, it is apparent that particle level curve of the captured image
     and decay curve of particle counter at 0.5μm overlaps.
