The UV300 is a cost effective water analyser for applications focused on one or two parameters.
Mainly based on UV spectroscopy, well known for its stability and low operating cost, the UV300 can measure parameters like organic matter, nitrate, colour, aromatics hydrocarbons (PAH).A complementary module allows the measurement of PO4, Cl2, NO2, Fe, Al by colorimetric method and turbidity by laser diode. External probes can be added for physicochemical parameters like pH, ORP, dissolved oxygen and conductivity. Thanks to its automatic cleaning system and its extremely long life time lamp, the maintenance is roughly limited to the periodic refill of the inexpensive cleaning solution. A new web-based interface allows the control and the troubleshooting from internet on laptop, tablet or i-phone.

The UV400, based on a modular concept, allows to monitor simultaneously many different parameters for waste water or drinking water treatment plants as well as river monitoring stations. Each parameter corresponds to a specific optical module that can be selected by the user while ordering the analyser, depending on the application. Mainly based on UV spectroscopy, well known for its stability and low operating cost, the UV400 can measure parameters like organic matter, ammonia, nitrate, aromatics hydrocarbons (PAH), colour, hydrogen sulphide and chlorophyll A. Complementary modules allows the measurement of phosphate by colorimetric method and turbidity by a visible or infra-red laser diode.

It allows to monitor simultaneously many different parameters for waste water treatment plants or river monitoring stations with an excellent stability and low operating cost. The same spectrograph can measure organic matter, nitrate, colour, turbidity, phosphate, ammonia and hydrogen sulphide. A complementary UV-visible fluorescence module allows the measurement of aromatics hydrocarbons (PAH). Nephelometric turbidity by visible or infra-red laser diode is also available. The full UV-visible spectrum can also be used to monitor specific chemical process making the UV500 a ideal instrument for chemical plants. Different materials are available for the flow cell and hydraulic parts depending on the matrix chemical compatibility. External probes can be added for physicochemical parameters like pH, ORP, dissolved oxygen, conductivity and turbidity. Thanks to its automatic cleaning system and its extremely long life time lamp, the maintenance is roughly limited to the periodic refill of the inexpensive cleaning solution and eventually reagents depending on the parameters.

Tethys Turbidity probes are based on Nephelometric Method (ISO 7027 – EN 27027). A light beam is sent to the sample through an optical lens. The 90 degree scattered light by suspended particle is collected by the probe through a second lens and it is converted in an electric signal proportional to the turbidity of the sample. The probe uses an infrared light and the measuring is not affected by the color of the sample. They are suitable for measurement of turbidity in water quality monitoring, municipal and industrial water treatment and Aquaculture.

 

Application:

  • Industrial waste water treatment plant
  • Municipal waste water treatment plant
  • Drinking water treatment plant
  • Surface water application
  • Other process water application
