Measuring instruments from WIKA undergo extensive in-house testing throughout their development cycle and beyond. This commitment to rigorous, impartial testing allows us to stand behind our claims of performance, durability, and reliability.<\/strong><\/p>\n

The data sheet for every WIKA measuring instrument contains a list of specs attesting to its accuracy, performance, and durability. But how do we back up those claims? With lots and lots of product testing, the vast majority of which is done in-house.<\/span>\u00a0<\/span><\/p>\n

WIKA\u2019s Comprehensive Quality Testing<\/h2>\n

We are passionate about product testing, so much so that we have our own certified labs dedicated to this function. These state-of-the-art facilities follow \u2013 and often exceed \u2013 national, regional, and global standards for safety and performance, and our testing experts are committed to impartiality.<\/span><\/p>\n

What\u2019s more, testing is not a one-time event at WIKA, but occurs from benchtop until shipping \u2013 and beyond.<\/span>\u00a0<\/span><\/p>\n

1. Prototyping<\/h3>\n

Our engineers love having a testing lab right on the premises. During the R&D phase, they are able to create a prototype, get immediate feedback on its performance, and then fine-tune the parameters. This reconfigure-and-retest process continues until the new model meets WIKA\u2019s high standards and expectations.<\/span>\u00a0<\/span><\/p>\n

2. Material quality<\/h3>\n

WIKA tests more than just products. When raw materials and components arrive at our facilities, our labs inspect and verify their quality before they hit the factory floor.<\/span><\/p>\n

3. Production<\/h3>\n

Once prototyping is complete and the materials are controlled for quality, it is time to assemble the sensors. Even during the manufacturing stage, our test labs are busy, pulling random samples to check the instrument\u2019s construction, mechanics, and sensor technology.<\/span><\/p>\n

4. Release<\/h3>\n

This is the stage where WIKA devotes the most time and attention. After a batch comes off the assembly line, we put large quantities of a particular sensor through the paces via sequential and parallel testing of its electronics, mechanics, and environment. This is one aspect of determining a product\u2019s PPM (parts per million defective) rating. WIKA proudly sets high quality standards with low PPM targets.<\/span><\/p>\n

5. Audits and service<\/h3>\n

Lastly, our test labs conduct annual audits on our sensors to ensure the quality of our instruments. And in the rare case of defects, we use scanning electron microscopes, digital microscopes, and other advanced equipment to analyze the product and determine the cause of the problem.<\/span><\/p>\n

Testing is an essential part of our company\u2019s DNA. We have a motto when it comes to quality assurance: It is better to test too much than too little.
