All Corrater probes have the economy of replaceable electrodes that double as corrosion coupons, providing a significant advantage over other electrochemical and electrochemical noise probe designs with fixed electrodes. The average corrosion rate of the electrode, determined as coupon, is correlated with that from the electrochemical measurements, allowing verification of all of the important empirical and electrochemical scaling factors, which cannot be achieved by electrochemical measurements alone.
Probes which are not removable under system pressure are sometimes used for reasons of economy, laboratory applications or special process limitations. These may be mounted with a flange or NPT threaded connection. NPT connections are available with fixed or adjustable length.
Corrater® probes are ideal for direct mounting into plant pipework or vessels and allow insertion or removal while under system pressure. The electrode seals are suitable for all pH ranges. These probes employ two replaceable, identical electrodes which are mounted at the end of the probe by ... [more]
Corrater Retrievable probes employ two identical electrodes which are mounted at the end of the probe by threaded, insulated, glass-sealed studs. The glass seals provide high pressure integrity. The probe is sealed into the hollow plug of the access fitting with a ceramic filled teflon seal. Two ... [more]
Temperature is one of the most important controllable factors affecting corrosion rate, particularly in refineries, chemical and petrochemical process plants. A rule of thumb is that corrosion rates double for each 10ºC temperature rise. The ability to rack temperature and corrosion rate ... [more]
The steel reinforcement in concrete structures is susceptible to corrosion when chloride ions enter into the concrete from de-icing salts applied to the concrete surface, or from seawater in marine environments. If chlorides are present in sufficient quantity, they disrupt the passive film on the ... [more]
CORROSOMETER® and CORROTEMP® CORROSOMETER® probes are designed for safe installation and operation in water applications. Certain accessories are required based on pressure, temperature, etc., including retractable probe safety clamps, intrinsic safety barriers, access valve assembly, ... [more]
RCS CORRATER® electrodes are manufactured from certified materials in a wide range of metals and alloys. A high quality 8-16 RMS surface finish and machined profile ensures uniform current density over the entire electrode surface. Electrodes are packaged in pairs with VCI (Vapor Corrosion ... [more]
