Tests for Consumers

Even though SENTEC is a high-tech company, a wide range of consumers also use our service, as we can confirm the composition of gold and silver bullions, as well as analyse collectables (coins, antiques) and jewellery. 


We can also check consumer goods for the presence of substances such as lead, arsenic, etc. banned by the RoHS directives
