Model LD-3B Digital Dust Monitor

The LD-3B is the latest model for measuring dust particles in the work environment. The LD-3B determines relative dust concentrations by measuring the intensity of laser beam scattered by dust.

Features
  • Provides 3 types of standard data output: RS232C, 0-1V voltage output and non voltage pulse output.
  • Easily convert mass concentration of measured value and diplay it by pre-setting a conversion factor for mass concentration.
  • Equipped with a recording function of measured value.
  • 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.
