We are the technology leader in the market and the partner to the gas and water supply industry
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.
