Six Core Advantages – A Promise of Unwavering Reliability
After ten years in sales, I’ve learned that what you really buy isn’t hardware—it’s peace of mind. This turbidity analyzer delivers exactly that through six thoughtfully engineered advantages. The dual optical path measurement acts like a meticulous editor, automatically compensating for turbidity interference to ensure your color readings remain pristine. Automatic temperature compensation is your silent guardian, correcting thermal drift before it can affect your data. Its strong anti-interference design makes this sensitive water detection sensor immune to the chaos of ambient light and electrical noise. We’ve included a wide-voltage power supply (DC 9~30V) because we know your sites aren’t always perfect. With high-resolution accuracy and an automatic cleaning function that prevents biofouling, this smart water monitoring device takes care of itself, functioning as a diligent turbidity tester that stays accurate without demanding your constant attention. It’s the reliable partner you deserve.

Colorimetric Sensor

Reagent-Free Absorption Spectroscopy – Monitoring in Harmony with Nature
True innovation respects the environment. Adopting the absorption spectroscopy principle, this turbidity tester requires zero chemical reagents, offering an eco-friendly, cost-effective solution that feels as pure as the water it monitors. The measurement process strictly complies with international colorimetric standards, ensuring every piece of data is valid and defensible. Visualize the water probe sensor gently submerged in clear blue water, performing real-time in-situ turbidity measurement without the hassle of sample preparation or lab delays. This continuous, maintenance-free approach makes it the beating heart of automated water detection systems, where rapid response and operational simplicity are paramount. Serving as a precise turbidity analyser, it allows you to focus on growth while it handles the monitoring, harmonizing technology with nature.

Dual Optical Path & Strong Anti-Interference – Seeing Truth Through the Chaos
In challenging environments where light fluctuates and waters turn murky, ordinary sensors lose their way. But this nephelometric turbidimeter is different. Utilizing modulated light signals, it cuts through visible light interference like a beacon. The innovative dual-path design specifically compensates for the effect of turbidity on color measurements, delivering results that are genuinely “More Sensitive” and “More Accurate.” Unlike traditional single-path sensors that might fail when you need them most, this turbidity probe thrives in fluctuating conditions. It stands as a robust water turbidity meter, capable of distinguishing between true color and suspended solids, making it essential for applications requiring high-fidelity turbidity monitoring. It’s about seeing the truth, no matter how cloudy the situation gets.

Biofouling and algae growth are the enemies of long-term deployment, but this turbidity analyser fights back with an internally integrated self-cleaning mechanism. Visually represented by a protective shield action amidst water ripples, this system effectively prevents biological accumulation on the optical window, much like a tireless caretaker. By minimizing the impact of fouling on measurement accuracy over time, it drastically reduces your maintenance costs and downtime. This feature is critical for long-term deployments in nutrient-rich waters, ensuring that your turbidity sensor remains clean and functional as a dependable part of any smart water monitoring network. It’s our way of ensuring you spend less time cleaning and more time succeeding.

Colorimetric Sensor

Wide-Voltage Power Supply – An Adaptable Energy Heart
Designed for versatility in power-constrained or remote locations, this water sensor probe supports a wide-range DC power input of 9~30V. We understand that not every site has stable electricity, so this flexibility allows the device to be powered by batteries, solar panels, or standard industrial supplies. Whether used as a nimble portable turbidimeter for field surveys or a fixed portable turbidity meter for permanent stations, the wide-voltage capability ensures uninterrupted operation. This adaptability enhances its role as a versatile water detection sensor in diverse infrastructural settings, proving that great technology should adapt to your world, not the other way around.

About - Water Color Sensor

Color is an important indicator of water pollution. High water color is usually caused by pollutants such as organic compounds and metal ions, which may affect human health, for example by causing digestive system diseases, and reduce the survival capacity of aquatic organisms. By measuring color, it is possible to determine whether natural water bodies are polluted or to prevent pollution by monitoring color changes. It can also be used to evaluate the effectiveness of wastewater treatment processes and to determine whether treated wastewater meets discharge standards.

特徴

How to calibrate the water color sensor?

Turbidity calibration

 

  1. Zero point calibration: Take an appropriate amount of zero turbidity solution in a beaker and place the color sensor vertically into the solution. Keep the electrode about 2 cm away from the beaker wall. After the reading becomes stable, perform zero point calibration. Refer to the register information in the product manual for the specific command.
  2. Second point calibration: Place the color sensor into a 500 NTU standard solution. After the reading becomes stable, perform second point calibration. Refer to the register information in the product manual for the specific command.

Color calibration

 

  1. Preparation of standard solution: Color standard stock solution equivalent to 500 degrees. Dissolve 1.245 ± 0.001 g of potassium hexachloroplatinate(IV) (K2PtCl6) and 1.000 ± 0.001 g of cobalt(II) chloride hexahydrate (CoCl2·6H2O) in about 500 mL of water, add 100 ± 1 mL of hydrochloric acid (ρ=1.18 g/mL), and dilute to the mark with water in a 1000 mL volumetric flask.
  2. Calibration (two point calibration): First, place the water color sensor into distilled water or deionized water, ensuring that the electrode is immersed at least 2 cm below the surface and that there are no air bubbles or obstructions in the optical path. After the reading becomes stable, perform zero point calibration according to the register command information in the manual. Then place the sensor into the 500 Hazen color standard solution. After the reading becomes stable, perform second point calibration according to the register command information.
  3. Note: During calibration, turbidity must be calibrated first, followed by color. Please wear gloves during operation.
