What kind of working environment should a hardness tester operate in?

Hardness is one of the commonly used indicators for evaluating the mechanical properties of metal materials. The essence of hardness is the ability of a material to resist the indentation of another harder material.
Hardness tester testing is a rapid, economical, and simple experimental method for evaluating the mechanical properties of metals. Its purpose is to determine the suitability of the material or the effect of special hardening or softening treatments performed for the material's intended use.
We should place the hardness tester in a dry and clean environment, far from damp places, and ensure indoor ventilation (use in a smoke-free location).
Commonly used hardness testers include Rockwell hardness testers, Vickers hardness testers, digital Rockwell hardness testers, Brinell hardness testers, etc.
