With regard to operational safety, test technology continues to grow in importance. The DVGW (German Technical and Scientific Association for Gas and Water) Code of Practice G 465-4 describes the tests required for various device classes.
The Sewerin test sets take these circumstances into account. For example, all test sets have a manometer for displaying can pressure and an improved can connection to make handling easier. An extensive range of accessories, e.g. test gas cans, results in a wide range of applications.
