Digital dust meter LD-5R is a relative co
ncentration meter ba
sed on the light scattering mode. Compared with the filter and capture method, it can complete dust measurement in a short time. In terms of characteristics, the relative co
ncentration obtained can be co
nverted into the mass co
ncentration by inputting the co
nversion coefficient (K value) of the mass co
ncentration obtained on the basis of filter and capture method.
PM2.5 digital dust meter LD-5R is based on LD-5R and equipped with PM2.5 cyclone separator type particle separation device, which can realize the simple determination of PM2.5.
