The sheath air mechanism enables stable measurements in workplaces with high concentrations of dust!
【Dust Collection and Removal Special Feature - Featured Equipment】 The LD-5D model utilizes a sheath air mechanism in the detection section and incorporates a built-in suction pump, enabling measurements in relatively high-concentration dust work environments such as tunnel construction sites. It is a relative concentration meter based on the light scattering method. 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 pre-inputting the mass concentration conversion coefficient. Additionally, 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.

basic information
Product Code: 20059 *Please provide this number when making inquiries for a smoother process. ◆ Thanks to the sheath air mechanism, stable measurements can be performed in high dust concentration work environments without worrying about contamination of the optical system. ◆ The use of a large filter allows for long-term use even in high concentration measurements. ◆ The degree of filter contamination is visible. ◆ By inputting the K value in advance, measurement values (CPM) can be converted and displayed as mass concentration (mg/m3). ◆ Automatic maintenance of the sensitivity at the time of shipment is achieved through "SPANCHECK" and "BG measurement" before measurement. ◆ Measurement values (CPM) can be recorded in the main unit (in logging measurement mode). ◆ Recorded measurement values can be imported and saved in text format on a PC using the included USB cable and communication software. *Compatible OS: Japanese Windows 98/Me/XP ◆ During measurement, voltage or pulses corresponding to the concentration are output. ◆ It can be mounted on commercially available tripods.
