DUST INDICATOR Model:LD-5D

DUST INDICATOR Model:LD-5D FOR HIGH CONCENTRATION Purged air Optics for Dust Purged air receiving light Light scattering plate Laser diode (light emitting part) Fine particle filter Photodiode for purged air (for receiving light) generation Filter Pump Output BlockDiaghram Large Filter Communication Cable with Software S-USB ■Purged air flow system enables the LD-5D to measure high 　concentration without contamination of its optics. ■Equipped with a large-sized filter for long term operation. ■Able to automatically convert CPM (count per minute) into 　mg/m3 by inserting a K factor.

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. ■Fe　atures ●The Model LD-5D can easily convert mass concentration ●The calibrated value is stored even after turning the of the measured value and display it by pre-setting a 　power supply off.
