Dust particle measurement devide

I need a dust measuring device that can do as follows please: The Dust Particle size must be PM2.5–PM10 microns, and the concentration range should be 0 µg/m³ to at least 50,000 µg/m³ or more, accumulating a Total Dust Count with fair accuracy over an 8 hour shift.The current sensors offer a maximum range of 0–1000 µg/m³ relating to only 1 mg/m³ Total Dust Count. The mine requires an alarm at 30 mg/m³. This means the dust level may exceed the alarm threshold, which we must be able to read

Hello,

Welcome to the TechForum.

I was able to locate some options that match some of what you are looking for but will require some datasheet scanning. Most of these have a datasheet attached to assist on the parameters.
