The products are equipped with color LCD displays that facilitate character recognition and the viewing of measurement results at dark measurement sites. In addition, they incorporate a LED indicator that indicate the operation status to allow operators to view the operation status from a location that is remote from the position where the indicator is placed.

Real-TIme Monitoring
They adopt the light scattering method to perform real time dust monitoring.

High Level of Measurement Precision
They adopt the purge air system to prevent dust in the sucked-in air from adhering to the optical system. After the end of measurement, it replaces the air inside the detector to maintain cleanliness and ensure outstanding durability.

Ease of Maintenance
For maintenance, it is sufficient to replace the cylindrical ilter and the circular filter. 
The sucked-in air passes through the cylindrical filter paper at the bottom of the main unit. This protects the pump from the dust that is sucked in. A circular filter paper is mounted on the outlet of the suction pump. The air that passes through this filter paper is supplied to the detector as purged air

Compact Size for Measurement
The size is 31% smaller and the weight is 0.6kg lower than the old model(LD-5)

Pump Suction System
The suction system employs a pump that is more powerful than a fan. That has paved the way for the stability of measurement and the attachment of a particle size selector.

Particle Size Selector
The right diagram portrays the correlations between the dust indicator with the PM2.5 particle size selector and the official method. The PM2.5 particle size selector employs the cyclone method to ensure very easy maintenance. As an option, a PM10 cyclone particle size selector is also available.
