While the portable dust meter of the past was convenient to carry, its short measurement time per session made it unsuitable for continuous monitoring. Additionally, to protect it from wind and rain, an external cabinet and sampling line are required when used outdoors.
The outdoor dust monitor, model FLD-1, is a dust monitoring device designed for continuous outdoor measurement by housing a light-scattering dust meter within a casing. With this device, dust concentration measurements can be conducted outdoors without the need for modifications or other adjustments. Additionally, thanks to its extensive output functions, it can be used for monitoring dust concentrations across multiple units at site boundaries, construction sites, and similar locations.
Features
●Various system configurations can be performed using the rich output functions.
●Since filter paper can be installed, this single device can be used for parallel measurement to determine the K value (mass concentration conversion coefficient).
●Spare filters and pumps are easy to replace, making maintenance simple.
●Reduce the increase in measurement values caused by fog, etc., by using a dehumidifying heater.
● Compact design for easy movement and installation.

■ Use imagery
In outdoor environments such as factory site boundaries, construction sites, and debris processing sites, one or more units can be installed. Utilizing the output function of this device, it can be used for centralized monitoring and issuing alarms when concentrations reach a certain level.
