Model LD-5D High Concentration Digital Dust Monitor

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.

Features
  • Model LD-5D can easily convert mass concentration of measured value and display it by pre-setting a conversion factor for mass concentration
  • The calibrated value is stored even after turning the power off. An automatic correction of measured value of aerosol will be performed by using data of calibrated value
  • Equipped with recording function of measured value
  • Provides 3 types of standard data output: USB interface output, 0-1V voltage output and non voltage pulse output.
