The LD-5D type is a relative concentration meter that employs a sheath air mechanism in the detection unit and incorporates a built-in suction pump, enabling measurements in relatively high dust concentration work environments such as tunnel construction sites. The relative concentration requires the determination of a mass concentration conversion coefficient (K value) based on the filtration collection method, and it needs to be corrected to mass concentration. However, the LD-5D allows for easy conversion and display of measurement values to mass concentration by inputting the mass concentration conversion coefficient in advance. Furthermore, it has similar characteristics to existing dust meters (laser light source type), allowing the use of previously established mass concentration conversion coefficients in the same work environment.
