Sentry Saf-T-Vise probes can be inserted and retracted within a pressurized system for applications that need continual or instant corrosion monitoring.
An electrical resistance (ER) probe measures both electrochemical and mechanical corrosion and is suited to corrosive environments with either poor or non-continuous electrolytes, such as vapors, gases, soils, wet hydrocarbons and nonaqueous liquids.
A linear polarization resistance (LPR) probe measures only electrochemical corrosion and is most effective in aqueous solutions, providing almost instant measurement of the corrosion rate. This allows an operator to evaluate changes or monitor the effectiveness of a chemical program and make adjustments quickly based on the probe readings.
The Saf-T-Vise STV-ER and STV-LPR probes offer a unique patented locking collet to hold the probe securely in the process stream. The probes are easy to place into and retrieve from a pressurized pipeline without interruption of the system. Either probe may be installed permanently to provide continuous information or may be portable to gather periodic data from several locations.
