Water Quality Sensor
Utilizing Multi-Spectral Technology to Support a Wide Range of Water Quality Parameters and Provide Accurate Readings
We develop sensors based on UV-Visible Full Spectrum Spectrometer and are able to measure multiple parameters in a single probe.
Why Use UV-Vis spectroscopy?
UV-Vis spectroscopy is a type of absorption spectroscopy, which utilizes the radiation in the UV range and adjacent visible range of the electromagnetic radiation spectrum. The absorption wavelength mainly ranges from 100 - 700 nm. This allows for a wide range of water characteristic detection from those that lie in the visible spectrum to UV spectrum. In addition, the high sensitivity, allows for the detection of low concentrations of contaminants. This precision is crucial for accurately assessing water quality.

Water Parameters Measured Using this Technology:
Turbidity
The turbidity is a measure of clarity of the water. It is the amount of light that is scattered by material in the water when a light is shined through the sample. High turbidity indicates polluted water due to vast number of suspended solids.
Nitrate
High levels of nitrate in drinking water, particularly in groundwater sources, can occur due to agricultural runoff, septic system discharges, and industrial activities. Nitrate in drinking water converts to nitrite within the human body and can be harmful as it interferes with oxygen capacity of red blood cells.
TOC
Total Organic Carbon (TOC) is a measurement of the total amount of carbon present in an organic compound in a water sample. TOC is a critical parameter in water quality analysis and is used to assess the amount of organic matter present in a given water sample.
COD
Chemical Oxygen Demand (COD) is a measure of the amount of oxygen required to chemically oxidize or break down organic and inorganic matter in water. COD is widely used as an indicator of the overall pollution level in water, particularly the amount of organic pollutants present.
