Dorsey Metrology International
The 14HE bench top comparator is Dorsey Metrology's basic and most economical comparator with the same high quality features as the other comparators in our product line, but in a smaller package and a lower price. The addition of our extra long life LED surface illumination is another Dorsey innovation.
