Titanium Spectrometer - Overview

This titanium spectrometer probe is a multi-parameter instrument that can measure multiple water quality parameters continuously. Its rugged design is suitable for use in high-pressure and high-temperature environments. As the probe comes into direct contact with the water, there is no need for complex sample pre-treatment. It is installed and operated by the easy "plug and measure" principle. The titanium spectrometer probes can be installed quickly and effortlessly, either submersed (InSitu) or in a flow-through setup (Bypass, monitoring station). It also comes with an automatic cleaning system that uses compressed air to clean the sensors. This system has proven highly efficient and reliable, even in untreated wastewater. The s::can spectrometer probes are intelligent instruments that use software-controlled procedures to identify any fouling on the measuring.

The titanium spectrometer monitors the following parameters depending on the applications selected: TSS, turbidity, NO3-N, COD, DOC, UV254, NO2-N, BOD, TOC, color, O3, HS-, BTX, AOC, fingerprints, and spectral alarms, temperature, and pressure.

Titanium Spectrometer - Features
- UV-Vis spectrometry over the total range (190-720 nm)
- Ideal for industrial wastewater, desalination, and seawater
- Rugged design with titanium grade 2 housing

Dissolved Oxygen Sensor | oxi::lyser DO
Call for price
Dissolved Oxygen Sensor - Overview

The oxi::lyser is in direct contact with the water and measures the concentration of dissolved oxygen and temperature. It needs minimal calibration and needs virtually zero maintenance. The oxi::lyser™ does not need a minimum flow to produce accurate readings and integrates the temperature measurement for online correction. The sensing element, which uses the principle of fluorescence for the oxygen measurement, is neither affected nor damaged by direct exposure to sunlight. To ensure that fouling is kept to a minimum, the oxi::lyser™ can be cleaned automatically with compressed air.

With a simple plug connection, which provides power supply and data communication, the oxi::lyser is connected to a s::can terminal and is ready for use. The “plug & measure” principle avoids complex installation procedures on-site and does not only save time during initial operation but also reduces avoidable errors. The optimised design eliminates all moving parts in contact with the water. This reduces failures and maintenance dramatically. Using standardised mounting devices installation is quick and effortless, either submersed (InSitu) or in a flow-through setup (by-pass, monitoring station).

The main application of the oxi::lyser is the online control of the most cost-intensive wastewater treatment process namely the aeration of the biological carbon as well as the removal of nitrogen. The activated sludge increases its activity with rising oxygen concentrations, but this increase is not linear: Above approximately 2.5 mg/L a further elevation in oxygen does not increase the nitrification enough to justify the rise in costs of aeration. Furthermore, too-high oxygen concentrations interfere with the process of denitrification. Therefore the oxygen concentration should be controlled online in the entire biological nitrogen removal process. Using the nitro::lyser™ and the ammo::lyser™ to monitor the nitrogen continuously in combination with the oxy::lyser, the operational procedures can be optimised.

In drinking water applications Dissolved Oxygen is mainly used in early warning systems detecting problems in raw water quality: Reduced dissolved oxygen concentrations are often an indicator of harmful microbial or chemical contaminations of the water.

Applied in natural waters or on fish farms the oxi::lyser™ can detect anaerobic conditions, which are life-threatening aquatic organisms, and thus it helps to prevent ecological as well as economic damage.
