This digital dust indicator is used to measure airborne particles at worksites.

1.Over view

  • This product is a dust indicator that makes use of scattered laser light.
  • The LD-5R is a relative concentration meter that uses the light scattering method, and is capable of displaying the measurement results in a variety of styles.
  • In comparison to the filtration collection method, a relative concentration indicator has the advantage of obtaining a large amount of data in a short time.

2. Main Features

  • It is small and lightweight, which simplifies transport and measurement layout procedures.
  • Since a color graphics LCD has been adopted for the display, visibility is excellent.
  • When the LCD screen is OFF, the operational status can be checked from a distance via the LED indicator.
  • The trend graph display is convenient for visualizing temporal fluctuations in dust concentration.
  • It is not necessary to move to a different screen to record the measurement data.
  • Filter replacement is easy and maintenance is simple.
