The Yaoan YRF100A High Concentration Dust Measuring Instrument is designed for continuous industrial monitoring of airborne dust mass concentration in environments where dust levels can be relatively high. It provides direct real-time readings and is suitable for factories, workshops, processing facilities and other industrial areas requiring dependable dust monitoring.
The instrument uses light-scattering and laser-based dust measurement technology together with a pumping system to detect airborne particles quickly and convert the measured concentration into a direct digital reading. Yaoan specifies a response time of less than 6 seconds and multiple configurable measuring ranges for different industrial dust applications.
A bright digital display shows the dust concentration directly in mg/m³, allowing operators to read measurements without additional equipment. The unit also supports audible and visual alarm functions, including configurable high and low warning levels, helping provide immediate notification when dust concentration exceeds the selected limit.
For industrial system integration, the YRF100A supports RS485 communication and standard 4-20 mA output, while LoRa and two-bus communication are listed as optional configurations. This allows the detector to connect with centralized monitoring, ventilation and industrial control systems.
The wall-mounted design simplifies fixed installation, while infrared remote-control operation allows parameters to be adjusted without opening the enclosure. With an IP65-rated housing and explosion-protected construction shown in the supplied product data, the YRF100A is suitable for demanding industrial dust-monitoring applications.
