90° Near-Infrared Light Scattering Digital TU Meter For Swage Water Detecting
Turbidity: refers to the degree of obstruction of the solution to the passage of light, also called turbidity.
Turbidity is caused by suspended substances such as sand, clay, organic matter, inorganic matter, plankton and microorganisms in the water, which can cause light to scatter or absorb.
At present, DRFN digital infrared turbidity analyzer uses the 90° near-infrared light scattering principle.
The intensity of the scattered light is compared with the intensity of the scattered light of the water sample. The greater the intensity of the scattered light, the higher the turbidity. On the contrary, the smaller Conform to the ISO7027 standard to measure the turbidity of water samples.
DRFN turbidity analyzer has many advantages such as good stability, low maintenance, and long life. It is widely used in industries such as surface and groundwater, municipal sewage, industrial wastewater, water treatment plants, sewage treatment plants, and process control.

Q1. What are the advantages of a digital turbidity meter?
A: The digital universal controller is matched with the corresponding digital sensor to realize the measurement. Compared with the traditional instrument and sensor combination, the biggest advantage is that the data transmitted from the sensor to the controller is more stable and accurate, the application is flexible, and the use is more convenient.
Q2. How does this turbidity controller collect data?
A: This digital turbidity meter is a single-parameter universal controller. Each controller will be pre-installed with a set of embedded software to correspond to different sensors. These connected sensors upload the detected data with a special encrypted communication method to ensure that the controller can collect high-precision data more stably. The controller will display the collected data on the display screen in real time, which is convenient for users to read.
Q3. Does the conductivity controller operation interface support customization?
Yes, our conductivity controller operation interface can be tailored to customers' needs.
Q4.Can customer's logo be added to the controller system and cover?
Of course, we support OEM services for customers. Both the boot interface and the controller shell can be added to the customer's logo, but there is a minimum order quantity requirement.
Q5.How long is the warranty period?
The company guarantees the instrument for one year (12 months) from the date of shippment, and the consumables and wearing parts in the equipment are not covered by the warranty.
Q6. Does the conductivity controller have an ambient temperature alarm function?
Our turbidity controller has ambient temperature alarm function, Can detect the temperature of the environment around the instrument
