Guides to choosing the right measurement method.
Before comparing models, settle the question that actually matters: which measurement method suits your material, your part and your application. Each guide ends by pointing you to the dmq line that fits.

Leeb or UCI: which hardness method to choose
Both are non-destructive hardness tests, but they don't give the same result on every part. The choice depends on size, mass and surface condition, not just the material.
Read the guideHall effect or ultrasound: how to measure thickness
Both measure wall thickness without damaging the part, but they don't travel the same way through every material. The choice depends on the material, the thickness and access to the part.
Read the guideMeasuring the paint or measuring the wall
On a painted part there are two different questions: how thick the coating is, and how thick the metal underneath is. Each one needs a different instrument.
Read the guideCast iron nodularity without breaking the part
How to classify grey or ductile iron and estimate nodularity from ultrasonic propagation velocity, with no destructive test.
Read the guideDoesn't your case fit any of these guides?
Tell us what material you need to measure, what the part is like and what accuracy you need. We'll suggest the model or models that fit, and why.
