Key features
Eyepiece Reticle with ruled grid and Globes/Circles for particle sizing and counting
The NG12 is particularly useful since the array of globes and circles are conveniently close to where the particles pass. At the end of each band of the sample the mechanical stage is traversed vertically to take in the next band until the whole sample has been covered.
