The technical quality and the safety of the Wika PSD-30 pressure switch has literally been sealed: The instrument has now been awarded the globally recognised cULus certification. UL Underwriters Laboratories Inc., one of the leading certification businesses for product safety worldwide, with its headquarters in the USA, has tested the pressure switch to the applicable US American and Canadian standards. The PSD-30 was tested for such things as pressure strength and ingress protection in installation conditions. Through the UL quality assessment for the switch, it will be considerably easier for customers to achieve regional approvals.
