assayers
Metal purity checkers
Assayers are people who test materials to determine their composition or quality.
The term most commonly applies to those who analyze precious metals like gold and silver, measuring purity and value: The assayers certified the gold at 99.9% pure.
More broadly, anyone who evaluates or appraises something may be called an assayer.
