Ranking among the very first enterprises specialising in industrial leakage-testing technology worldwide, it is with pride and gratitude that we announce our fiftieth anniversary.

Above all our gratitude goes to our many long-standing customers all over the world who have remained loyal to Dr. Wiesner – in some cases for whole decades – and who have come to appreciate the high quality standards applied to both our products and comprehensive range of services.

A further debt of gratitude is owed to the excellent bonds of cooperation maintained with our business partners and suppliers who ensure that our products can always be delivered bang on schedule.

We have equally just reason to be grateful to our staff, whose expertise, commitment and untiring devotion is convincingly demonstrated day in, day out and who make a magnificent contribution to the success enjoyed by our company.

It is our avowed objective to continue meeting the high quality demands imposed on ourselves and our products and to gear future developments to the same unrelenting standards – all for the benefit of our customers.
