Knick Interface offers a five year warranty for all products.
The Knick quality management has been certified according to ISO 9001 for all areas of the company and has also contributed to Knick being certified according to KTA 1401 as a recognized supplier of isolation amplifiers for use in nuclear power stations since 1994. Additional corresponding certifications related to individual safety-related areas of nuclear power plants have also been issued.
Intelligent circuits with minimal use of components allow reliability values that were previously considered to be impossible – for example, the MTBF (Mean Time Between Failures) of the VariTrans B 10000 standard-signal isolator is 440 years.
The quality of all Knick products is ensured by computer-supported individual testing. For the isolation modules, this means that each individual device is checked again for perfect functioning and compliance with all data after the functional test, adjustment, encapsulation where necessary, and high-voltage testing. Only then is the device released for delivery.
