On-Line Metal Monitoring

On-Line Heavy/Trace Metal Monitoring with our OVA7000 Dual Cell Analyser system.

Monitoring trace/heavy metals was an important process and environmental parameter world wide - and today is probably a critical measurement. With our Modern Water OVA7000 Dual Cell Analyser system, we are able to offer customers real time 24/7 analysis of these important parameters. Up to 10 different metals can be monitored on one Analyser system. It is also possible to offer speciation on certain metals such as As(III); Cr(VI); Sb(III) and Se(V).  

Detection limits go down to parts per billion (ppb / µg/L) and turbidity or colour does not affect the method. Power options for the Analyser range from 12VDC and 90-240VAC which makes this a truly versatile Analyser for any site in these power deficient times.

Samples range from waste water, process water, river water to drinking water. 

Process Explained: 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.  Each metal has a specific voltage at which it returns to solution, so the metal is identified by its stripping voltage, and the current generated indicates the concentration of the metal in the sample.   OVA Dual Cell Specifications: Configuration: Two analytical cells with LCD screen for each cell.  IP 65 Rating Power Supply: 12VDC, 90-240 VAC Communication and Outputs: LAN, Modbus, TCP/IP, WiFi, USB, RS232 with the option of 4-20mA
