The 9030 Plus Instrument is a corrosion rate system designed for cooling water, process water, and feed water systems. It is available with one or two channels of corrosion rate, imbalance, and temperature data for rapid response to process upset conditions. Two-channel operation allows for the monitoring of two alloys at a time, for example, mild steel and a copper-based alloy (found in many plant systems). The 9030 Plus Instrument's patented Solution Resistance Compensation uses Electrochemical Impedance Spectroscopy (EIS) to improve the accuracy and extend the range of Linear Polarization Resistance (LPR) corrosion monitoring, increasing the operating range up to 20 times more than competitive instruments. This greatly improves the applicability of the instrument for monitoring lower-conductivity waters and provides superior performance over standard three-electrode systems. In addition, the 9030 Plus Instrument takes a sample of Electrochemical Current Noise (ECN) between the electrodes, and displays the ECN data as imbalance. The imbalance current is related to pitting, corrosion activity and inhibitor film stability. The 9030 Plus Instrument is capable of monitoring temperature when a CORROTEMP® CORRATER probe is used instead of a CORRATER probe. The data logging function is activated through a RS-232 serial port directly from a laptop or desktop PC using CORRDATA®Plus Software. The software is Windows® XP Pro/Vista Business/Vista Ultimate compatible. Features of the software include: - Powerful graphical displays - Easy analysis to calculate average corrosion rates - Graph annotations - Easy transfer of graphs to word processing programs Six electrically isolated 4-20 mA outputs are available for connection to recorders, control systems, or computers. Safety barriers, available as optional equipment, permit the 9030 Plus instrument to be used with probes located in hazardous areas.
