It is an online dust meter that measures the mass concentration of dust, particles, aerosols, and other substances in the air in real time.

Delivery will begin in November 2021. ■ This sensor can monitor two aspects of suspended particles in the atmosphere and space: the number and mass concentration of "dust" and "fine particles." ■ It can measure particle sizes from 0.3 to 10µm and continuously measure mass concentrations up to 1000µg/m³ in real-time. ■ The measured particle count and mass concentration can be output as an analog signal (DC4-20mA), and by setting a threshold, alarm contacts can also be output. ■ It is equipped with a Wi-Fi module, allowing you to change device settings and check measurement values via a web browser if you have a Wi-Fi-enabled device (PC, smartphone, tablet, etc.) at hand. Okuno Electric Co., Ltd. is the official distributor of Matsushima Majatech Co., Ltd. Matsushima Majatech website: https://www.matsushima-m-tech.com/

Applications/Examples of results

■Monitor the level of dirt in indoor spaces and contribute to cost reduction and energy savings through fan rotation control, airflow control, and power management. ■Monitor the level of dirt in spaces such as offices and visualize the cleanliness of the indoor environment, contributing to the creation and maintenance of a healthy environment. ■Measure the dust generation in places where people gather, such as commercial facilities and mass retailers, contributing to the prevention of crowding. ■Monitor the cleanliness in clean manufacturing environments for precision products, contributing to the maintenance and management of quality. ■Monitor "human movement" and "inflow of dirty air" in clean rooms and workspaces, contributing to the investigation of causes in routine daily operations and work outside of business hours.
