High Concentration Digital Dust Indicator

1. Overview

• The LD-5D is an aerosol photometer designed to read relative mass concentration of aerosol in high concentration. It is
  designed to read mg/m3 directly, however it should be remembered that the calibration is strictly valid for the calibration
  particle. To measure the accurate mass concentration of the aerosol at hand, a comparison measurement using the
  gravimetric method will be needed to convert a conversion factor (so called the K factor) to the instrument.
• Equipped with a recording function (logging function) of the measured value
• The Model LD-5D can easily convert mass concentration of the measured value and display it by pre-setting a conversion factor for mass concentration
• The calibrated value is stored even after turning the power supply off. An automatic correction of the measured value of aerosol will be performed by using data of calibrated value
• Provides 3 types of standard data output: USB interface output, voltage output (0-1V) and non voltage pulse output (open collector)
