Clear 0.1ml 0.2ml 8 Strip PCR Tubes for PCR Instrument Polypropylene Thin Wall
The MS500-PM Portable Laser Particulate Matter Detector is designed for on-site measurement of airborne particles in industrial and environmental applications. Using laser-based sensing technology, the instrument measures PM2.5 and PM10 particulate concentrations and provides readings through a color digital display.
A built-in pump continuously draws ambient air into the measurement system. The detector offers a measurement range of 0–1,000 µg/m³ for both particulate categories, with a resolution of 1 µg/m³.
The instrument is equipped with configurable alarm functions, internal data storage and a USB interface for communication and charging. Optional wireless transmission modules allow the system to be configured for additional monitoring requirements.
Its portable construction, rechargeable lithium battery and IP66-rated enclosure support field inspections across industrial and outdoor environments.

Environmental field monitoring
Factory dust inspection
Manufacturing workshops
Industrial park surveys
Outdoor particle concentration measurement
Warehouse and storage area inspection
The MS500-PM combines laser particulate sensing, active air sampling and local measurement storage within one portable detector.
Its dual-parameter monitoring capability makes it suitable for field applications requiring PM2.5 and PM10 concentration measurements without using separate instruments for the two particle categories.
