Description
The Precont® D40 is used in all fields of proceeding and process technique.
The excellent characteristics like pressure strength, high chemical resistance, corrosion protection and insensitivity against temperature shocks allows the use in the hardest applications for the measurement of gases, steams and liquids.
By the special contruction the device is especially suitable for the use in areas witht hight air humidity and at condensed water formation where conventional devices can not or can only be used with an expensive placed air compensation capillary.
