Laser Flow-through Turbidity Sensor for Drinking Water

For low-range turbidity measurement, the choice of turbidity light source is very critical. Traditional light source are generally based on infrared LED emitters and halogen tungsten cycle incandescent lamps. Infrared LED emitters have low brightness, low light efficiency, poor directionality, and large errors in specific wavelengths. Halogen tungsten lamps have poor shock resistance, short life, and high heat generation. They can easily heat up the sample, stimulate the liquid sample to precipitate bubbles, and interfere with the measurement. The laser light source is considered to be the most ideal light source substitute that can meet higher detection requirements. Laser is a light source generated by stimulated radiation. It has good directionality, single beam, and concentrated frequency. It is mainly a single wavelength of light, and the error of light at a specific wavelength is very small.

What are the advantages of the flow-through OLTU600 low Turbidity Sensor?

The flow-through scattering turbidity sensor requires a container for the sample to be measured. The main purpose of the container is isolate the interference of external light on the measurement. Another main purpose is to stabilize the flow rate, precipitate and release bubbles in the water. Since a certain ammount of sample is required for the flow-through detection of samples, miniaturization is the key to reducing sample consumption. Daruifuno's OLTU600 turbidity sensor only requires a flow rate of 100mL/min to achieve stable measurement, greatly reducing the dependence on sample volume. In order to prevent the sedimentation of suspended matter caused by low flow rate, we invented a stream-like sample runway for this purpose. The sample runway has certain regular bottom heights and low protrusions to form local turbulence and slow flow effects and evenly stir the sample to push the suspended matter to prevent sedimentation. On the other hand, the runway surface area is expanded, which is conducive to the sample to release pressure and precipitate bubbles.

Specification

Daruifuno's laser online low turbidity sensor can be used with the DUC2-TU single-channel low Turbidity Controller or the multi-channel controller MCC200 to achieve integrated multi-parameter online monitoring. For example, in the monitoring of swimming pool water or drinking water, the low range turbidimeter can be used with a PH Sensor or a residual Chlorine Sensor. Delfino focuses on the research and development and production of water quality instruments. Our main products include pH ORP analyzer, conductivity analyzer, turbidity analyzer, COD analyzer, dissolved oxygen analyzer, ammonia analyzer, chlorine analyzer, etc. If you are interested in water quality analysis instruments, please contact us.
