Water Quality Measuring Technology
Water quality measurement and monitoring are implemented in a variety of applications through the use of varied optical measurement technologies.
Accurate measuring and simple monitoring of water quality by original technology of Optex
Technology to measure water quality such as turbidity and color
Water quality of substances, such as turbidity and color, can be measured according to the characteristics/ properties of the target substances by combining measuring light sources of various wavelengths and light measurement methods with original know-how of Optex.
|Measuring transmitted light||Measuring scattered light||Measuring weak luminescence|
The intensity of light transmitted through a sample is measured.
The intensity of light scattered by particles in a water sample is measured.
The intensity of weak luminescence emitted from the water sample itself is measured.
Optex products applying the transmitted light method (Turbidity Checker Series)
Light is projected in the direction of an arrow, and amount of transmitted light is converted into the degree of turbidity or color.
A variety of technology of Optex enables the accurate measurement of water quality
Minimizing effects resulting from the deterioration of LED light source
The adoption of reference light technology, which is less susceptible to even minute deterioration, by making a long-life LED light source further receive reference illuminants.
Pulse signal control less susceptible to ambient light
Transmit the pulse of light sources (ON), and grasp the level of ambient light at the time of non-transmission (OFF)
By processing only the difference of ON/OFF, the effects of ambient light are eliminated.
Stable measuring is ensured, indoors or outdoors
The stable measuring of water quality in harsh environments is realized.
In order to realize safe and reliable continuous water quality monitoring, the dirt-resistant wiper control system developed by Optex and scratch-resistant sapphire have been adopted.
Periodically removing dirt from the surface of the lens solves the problem of scratches on the lens surface caused by minerals or sand present in measuring environment.
Maintenance is also easy.
Easy to handle “compact design”
The most compact device in Japan ('*comes with a wiper cleaning device)
The volume ratio of the compact sensor (right)*, less than 70% of that of a conventional sensor (left), was realized ,
