Wetted materials of construction are 316 stainless steel and Teflon, with double O-ring seals at all points. The first EPR O-ring bears the brunt of process interface, allowing the second O-ring to maintain reliable sealing, free from chemical attack. An integral temperature element allows automatic compensation for maximum accuracy. Leads are 10 ft./3 meters standard. Process connections are made via a bored through swage 3/4� NPT fitting as standard. This fitting may be installed into a line or tank, or may be reversed and connected to a standpipe for use in a submersion configuration.
