HONSBERG

Honsberg in Remscheid has ensured high-quality products in measuring and monitoring technology since 1963.

Their devices measure and monitor flow, level, pressure and temperature. Consequently, they supply the market in various areas and applications, including wastewater treatment plants, diesel engines, hardening facilities, compressors and construction machines, machine tools, paper and print machines, and cooling systems.

Customers rely on the excellent quality of their products in all of these areas and applications. In addition, they develop customised solutions for customer-specific applications in their R&D department to suit various requirements.

Their measuring instruments are manufactured in their factory in Remscheid to the highest quality standards. As a result, their measuring instruments feature high-quality workmanship, the best materials, and consistently outstanding measurement accuracy, durability, and resistance.

It is precisely the harsh conditions our customers place on Honsberg products that their high-quality equipment must withstand. After all, this is why Honsberg develops, manufactures, and tests them themselves.
