About

Swiss based Trafag offers precise, reliable and maintenance-free instruments developed for density monitoring of SF and related alternative gases. Monitoring is based on the gas density reference principle. The arctic monitor is based on the gas density reference principle and reliably keeps the liquefaction alarm status until it returns to normal condition. Thus offering the most reliable solution on the market by directly monitoring the insulating gas density.
