High And Low Alarm OTA 4000NTU Turbidity Transmitter For Industrial Sewage
Online turbidity is the degree of obstruction that occurs when suspended matter in water transmits light.
The presence of soil, silt, fine organic matter and other microorganisms and colloids in the water can cause turbidity in the water. After the light wave sent by the transmitter on the sensor is absorbed, reflected and scattered by the measured object during the transmission process, part of the transmitted light can illuminate the detector in the 180° direction, and part of the scattered light is scattered to the detector in the 90° direction. superior.
The light intensity received on the 180° and 90° direction detectors has a certain relationship with the turbidity of the measured sewage, so the turbidity of the sewage can be calculated by measuring the intensity of the transmitted light and scattered light.

Q1. What are the advantages of a digital turbidity meter?
A: The digital universal controller is matched with the corresponding digital sensor for detecting. 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. Can customer's logo be added to the turbidity controller system and cover?
Of course, we support OEM services for customers. Both the boot interface and the turbidity controller shell can be added to the customer's logo, but there is a MOQ requirement.
Q4. Does the turbidity controller have an ambient temperature alarm function?
Our Turbidity controller has ambient temperature alarm function, it can detect the temperature of the surrounding environment when the controller is used.
Q5: The turbidity controller with OTA function?
Yes. Our DUC2-LTU-S-D turbidity controller Default with OTA
