DRI-CAL™ Particle Size Standards

 

Size Standards for calibrating particle counters which require dry particles, from 5 to 100 micrometers µm.

They are packaged in dropper-tipped vials in 1 gram quantities, in order to dispense them directly into the sampling chamber.

They are not suitable for dispersion in liquid media. The mean diameters are traceable to the National Institute of Standards and Technology (NIST).
