The Effects of Carryover in Steam Boiler Systems

The occurrence of boiler water carryover can usually be verified by testing the condensate. As a general rule, low conductivity condensate (less than 25 µmhos) indicates high purity steam is being produced while high conductivity condensate (greater than 25 µmhos) indicates the presence of carryover.
