Online Trace Metal Monitoring Systems
Automated Trace Metal Monitoring - OVA7000
Fully Automated On-Line monitoring is possible with our OVA7000, OVA7000 Dual Cell and OVA5000 Trace / Heavy Metal Analyser systems. These fully automated on-line metal monitors enables municipalities, industries and environmental agencies to continuously determine the levels of trace metals in process streams, effluent discharges, rivers and potable water.
The OVA7000 has a built in PC, which can be controlled by a computer connected via Wi-Fi or LAN. This external control prevents unauthorised users from making any changes. The Analyser system is housed in a modular cabinet with a seperate reagent cabinet.
The OVA7000 Analyzer system runs on low power 12V DC (or standard 90 - 260V AC), making it the ideal solution for remote locations.
In Voltammetry metals are drawn onto the working electrode when a specific voltage is applied to the water sample under test.
When a stripping voltage is applied, the metals return to the sample solution, generating a small current. Eash metal has a specific voltage at which it returns to solution. So the metal is identified by its stripping boltage and the current generated indicates the concentration of metal in the sample.
