The LD-5D model, which uses the light-scattering method, is a dust monitor for high-concentration environments such as at water supply construction sites. With its sheath air mechanism and built-in suction pump, this model demonstrates stable operation in high-concentration environments. The LD-5D is compatible with the LD-5 dust meter (laser light source), although it has only 1/10 of the measuring sensitivity of the LD-5D. Able to measure up to 100mg/m³. [Features] • With large filter → Long-lasting under high-concentration conditions → Easy detection of filter clogs • CPM readings are converted and displayed in mass concentration (mg/m³) • CPM readings can be stored in the body (in logging measuring mode) • Captured data can be transferred to a PC for further processing in text format using S-USB cable and data transfer software • Can be used with commercially available tripods * For more details, please contact us or download our catalogs.
