RS485 Interface OTA Infrared Turbidity Transmitter For Swage Water Measuring
The digital laser turbidity analyzer adopts 660nm laser light source to measure turbidity of water samples.
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.
Modern turbidity detection technology is developing rapidly, and turbidity meters for various purposes, such as laboratory instruments, online analyzers, portable turbidity meters, and ultra-low turbidity laser turbidity meters, have come out one after another.
At present, the turbidity detection generally uses the 90° scattering method, that is, under the same conditions, the intensity of the scattered light of the formazin standard suspension is compared with the intensity of the scattered light of the water sample, the greater the intensity of scattered light, the higher the turbidity.

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. 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.
Q4. 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.
