Digital Dust Indicator

1. Overview

• The LD-5R digital dust indicator is a relative concentration meter based on the light scattering method. It measures the dust level in less time than the filtrated collection method. Due to its characteristics, the relative concentration may be converted into mass concentration with the use of the coefficient of conversion into mass concentration (K factor) calculated based on the filtrated collection method.
• The LD-5R PM2.5 digital dust indicator is a combination of the LD-5R with a PM2.5 cyclone particle size selector to perform the simplified measurement of PM2.5 concentrations.

2. Features

• Display: The products are equipped with color LCD displays that facilitate character recognition and the viewing of measurement results at dark measurement sites
• 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 the measurement, it replaces the air inside the detector to maintain cleanliness and ensure outstanding durability
• Ease of maintenance.
• Compact size for measurement.
• 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 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.
