For high concentration environmental measurement! This is a product certified by the Japan Association for Working Environment Measurement.
The "LD-5D type" is a dust meter using light scattering method that can measure in high concentration environments such as tunnel construction work. It is equipped with a sheath air mechanism and a suction pump, allowing for stable measurements even in high concentration environments. It is compatible with dust meters like the LD-5 type (laser light source type) at 1/10 sensitivity. It can measure up to 100 mg/m³. 【Features】 ○ Adoption of a large filter → Long-term use is possible even in high concentration measurements → The condition of the filter can be easily checked from the outside ○ Measurement values (CPM) can be converted and displayed as mass concentration (mg/m³) ○ 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 S-USB cable and communication software ○ Can be mounted on commercially available tripods For more details, please contact us or download the catalog.

Company information
Our company was founded in 1921 in Hongo, Bunkyo-ku, Tokyo, as a manufacturer and seller of scientific and medical glass instruments. Since then, we have developed "general scientific instrument products" to support research and development for government agencies, universities, and various companies. In response to the growing demand for environmental monitoring and measurement in areas such as occupational health, air quality, and water pollution, we have also developed "environmental measurement instrument products." Additionally, we have responded to various needs in the chemical and pharmaceutical fields by developing "large chemical plant equipment," "animal experimentation equipment," and more, leading us to the present day. As we live in the 21st century, we have a mission to protect a rich and habitable Earth for everyone and to pass it on to future generations. Various environmental conservation actions based on this awareness are now being implemented worldwide. At Shibata Scientific, we continue to create products that contribute to environmental conservation, leveraging over 80 years of experience and technology in this field. Moving forward, we will continue to refine Shibata Scientific's technology, quality, and trust to contribute to the advancement of global science and technology and the protection of the Earth's environment.
