Ductility Testing with Humboldt Solutions
- October 5th, 2020
- Category: Equipment Guides
What is Ductility Testing? Materials that are capable of deforming plastically before fracturing are defined as ductile. Ductile testing, therefore, involves measuring the amount of stress that can be applied to a material without fracture. Why is Ductile Testing Important? Ductile testing will tell you the tensile strength of... Read more >
Hydrometer Analysis with Humboldt Solutions
- August 26th, 2020
- Category: Equipment Guides
What is a Hydrometer? Hydrometers are used to measure the relative density of a liquid. They are primarily made of glass and have two parts: the hydrometer with a mercury weighted bulb at the bottom and a cylinder with graduation marks. The science behind the hydrometer is simple – the lower the density of the liquid, the more... Read more >
