Digital Dust Indicator LD-5D

● Thanks to the sheathed air mechanism, there are no concerns about contamination of the optical system, and it can be used to provide stable measurements at work sites with high dust concentrations.
● A large filter has been adopted, so it is capable of extended use even for high concentration measurements.
● The extent of filter contamination can be confirmed visually.
● Entering a K value in advance enables the measurement value (CPM) displayed to be converted to mass concentration (mg/m3).
● A span check and background measurement prior to dust measurements automatically maintain the sensitivity at time of shipment.
● Measurement values (CPM) can be recorded in the main unit. (In logging measurement mode)
● The recorded measurement values can be loaded into a PC and saved in text format using the USB cable and communication software provided.
● During measurement, a voltage or pulse corresponding to the concentration is output.
● It can be powered by dry cells or an AC adapter.
● It can be attached to a commercially available tripod.
