Instrument Overview

Modern Water's online monitoring system has been tested in practice and has led the monitoring technology in this field for 20 years. Our online monitoring system can perform real-time continuous monitoring, providing reliable data basis for quick decision-making. Compared to conventional laboratory monitoring, using OVA can save operating and consumable costs, and ensure timely compliance with emissions standards through real-time monitoring, avoiding the loss of fines. The OVA system can be easily integrated into existing process monitoring systems.

Instrument method

anodic stripping voltammetry

Voltammetry uses the principle that metals in water samples are attracted to the working electrode at a specific voltage to detect metals. When the dissolution voltage is applied to the electrode, the metal will return to the sample solution and a weak current will occur. Each metal has a specific dissolution voltage. So, the type of metal is determined by the dissolution voltage value, while the current intensity corresponds to the concentration of the metal in the sample.

Instrument features

• Monitor 3-6 samples continuously for 24 hours (depending on the type of sample).
• Lightweight construction, modular design, separated analysis and reagent compartments.
• The measurement results are stored in a solid-state memory.
• An alarm can be issued for abnormal measurement results or system anomalies.
• Solid electrode - does not contain venom body mercury.
• Can be set to monitor multiple metals simultaneously.
