Many digital dust meters are used to measure suspended particulate matter related to the built environment and other factors. They offer advantages. On the other hand, it is necessary to calculate the mass concentration conversion coefficient based on the filtration method and correct the obtained relative concentration to the mass concentration.
The mass concentration conversion coefficient (K value) of the LD-3S model adopts a switching method between "1.3 (0.0013)" and "1.0 (0.001)", making it easier to operate through measurements in building and school environments.

● Further reduction in size and weight has been achieved, with a volume ratio of approximately 63% compared to the traditional LD-3C model.
● After the measurement is completed, the mass concentration (mg/m³) and count value reflecting the set K value will be displayed.
●Operate easily with just two buttons. Complex functions are omitted, and the operability makes measurement simple.
●The color of the LED indicator allows you to check whether a measurement is in progress even from a distance.
