Experts opinion

At SurTec we produce and sell chemicals for industrial and electro-chemical protection – galvanisation of metals. The successful marketing of our products is closely connected with technical support for our customers in the form of surface protection testing. When we encounter a situation which calls for a quick response in the central European region we choose LOTRIČ Metrology. We value their business-like manner, professionalism and their dedication. They are a suitable partner for all companies which must ensure quality of their products. For instance, they have helped us solve our problem of acid zinc blistering where only their measurements and tests showed the source of our problem - the low quality raw material.

Edi Kokalj, managing director CE Europe at SurTec International GmbH – Brand of Freudenberg

We have been working with LOTRIČ Metrology group for some years now on the testing of galvanised protective coating, analysis of raw materials and monitoring of waste water. Analysis is done when developing and launching new products for clients in the automotive industry, such VW,Daimler, Audi, BMW and PSA which have to meet very precise standards. We also use the test results for the optimisation and improvement of production processes. The great advantage of working together with LOTRIČ Metrology group is the proximity of their laboratory, the technical knowhow of their experts and their quick response time. A great added value are their certificates on performed analyses with included justification as they help us gain more business opportunities.
