Continuous Measurement

If you want to improve, you must measure. Online water quality measurement has many advantages. Continuous monitoring systems recognise the changing process water conditions as they occur, allowing immediate corrective actions.

Adjustable Frequency of Analysis

The actual DOES® water quality analysis takes just a few seconds. In addition, the system automatically cleans and assures the analytical quality between the measurements resulting in a typical measurement interval of 5 — 30 minutes.

Depending on the measurement frequency, the maintenance interval can be extended to 3+ months.

Low Cost of Ownership

Because the Micro-discharge is directly created inside the water sample, there is no need for carrier gas like argon which is typically used in ICP-OES and ICP-MS laboratory equipment. Both ICP-OES and ICP-MS can consume 15–20 L/min of argon gas resulting in up to €15 000 annual savings potential when using µDOES® in continuous process monitoring.

Compared to traditional inorganic analytical methods, Sensmet µDOES® technology does not require any expensive or hazardous chemical reagents for the analysis.


With Sensmet’s cloud solution you can follow the measurement results and trends in real-time with any device of choice. Furthermore, we can perform troubleshooting as well as remote maintenance and assistance as needed
