Accreditation as calibration laboratory for quantities of heat Lorem ipsum dolor sit amet consectetur. Consectetur augue mus sit in id. Aliquet sed sit condimentum consectetur molestie pellentesque bibendum porttitor elementum.

The Sontex calibration laboratory SCS 0071 has been accredited since 1996 by the Swiss Accreditation Service SAS to ISO/IEC standard 17025, with periodic monitoring (see accreditation certificate and SCS directory). The lab is equipped with several water testing stations from 15°C to 85°C for flows of 5 litres/hour to 200 cubic meters/hour with ANSI threaded connections from ¾” to 2” and DIN flange joints from DN 15 to 150, as well as temperature baths for temperature difference measurement between 5°C and 150°C with a temperature difference of at least 1 K T. The publication of trilingual measurement certificates is an important part of what is offered.
