Corrosion detector Saf-T-Vise

polarizationelectrochemicalresistance

entry Saf-T-Vise probes can be inserted and retracted within a pressurized system for applications that need continuous or one-time corrosion monitoring. An electrical resistance (ER) probe measures two types of corrosion, electrochemical and mechanical. It works in environments that have poor or non-continuous electrolytes, such as vapors, gases, soils, wet hydrocarbons and nonaqueous liquids. These conditions enable the material to corrode. A linear polarization resistance (LPR) probe measures the electrochemical type of corrosion and is most effective in water-based solutions. This type of probe provides a near-instant measurement of the corrosion rate. Knowing the corrosion rate at a given moment allows an operator to monitor the effectiveness of a chemical program, propose changes, and make adjustments quickly based on the probe readings. The Saf-T-Vise STV-ER and STV-LPR probes offer a unique, patented safety feature to increase operator safety: an easy-to-use collet that locks the shaft within the process stream in both low and extremely high-pressure conditions. The probes are easy to insert and remove from a pressurized pipeline without interruption of the system. The Saf-T-Vise probes may be installed permanently to provide continuous information or portable to gather on-demand data from multiple locations. Benefits To avoid corrosion and equipment damage and enable accurate monitoring, Saf-T-Vise has a materials certification and test summary to confirm the product’s materials. These documents improve material traceability to meet the requirements.
