    Traditionally the dew point of SF6 has been measured by taking a gas sample from the tank, meaning that there has always been gas flow to account for during these measure-ments. Gas flow conceals the effect of very slow diffusion and vapor transients between gas and solid materials. To date it has been quite common for dew point sensors to be installed in the same sensor block as pressure relays or density sensors.
