A durometer is an instrument that is used to measure hardness. Specifically, a durometer can be used to measure a material's resistance to indentation.
==Durometer== The Durometer returns a dimensionless (or unitless) value that ranges from zero to 100. It measures hardness and is limited to use with rubbers and polymers. Wikipedia has an article on the Shore Durometer.

90 durometer
Durometer
The letter behind the number refers to the durometer "hardness" of the wheel. In the case of the wheel in question, it must be a dual durometer wheel, meaning the core is harder than the outer part of the wheel.

basically, 70 mm is the diameter of wheel. wheels can range from 65mm-100mm. and the other number is the durometer. used to determine the hardness of the wheel. it's easy to tell which number is the durometer, because it will always have the letter "a" after it. ex: 76a, 88a, 90a. Durometer ranges from mid 70's all the way to 90's. the higher the number, the harder the wheel. it's useful to know this because the softer the wheel, the more grip you will have, and the harder it will be to break traction and slide. and it's the opposite with harder wheels. so 83a is almost in the middle, so it's pretty much okay for anything. : )
One of the scales is a durometer. The appropriate scale depends on the industry the hardness is being tested for.
The hardness of the rubber. Softer rubber gives better grip on rock, but wear faster.
They are used to measure weight.
A barometer is used to measure atmospheric pressure. It can also measure altitude!
A balance is used to measure mass.
