LowTuS: low range turbidimeter

Aqualabo’s LowTuS turbidity probe employs an ISO 7027 compliant nephelometric method, ensuring precise turbidity measurements from 0 to 100 NTU. Its unique self-cleaning mechanism guarantees sustained accuracy in time.

NTU Probe

Aqualabo’s NTU optical turbidity probe measurement principle is based on the 90° infrared light-scattering nephelometry. A wide range of 0 to 4000 NTU, ensures accuracy in diverse water quality applications.

Why measure turbidity in water?

Turbidity serves as a crucial parameter in water quality assessment, playing a pivotal role in understanding the health and safety of water sources. Elevated turbidity levels can indicate the presence of suspended particles, sediment, or pollutants that may compromise water quality. Monitoring turbidity is imperative for regulatory compliance in both drinking and wastewater and ensures the effectiveness of water treatment processes. Digital and optical probes facilitate precise turbidity measurements, empowering industries and municipalities to proactively manage water quality, mitigate environmental impact, and safeguard public health. Accurate turbidity data not only ensures compliance with stringent standards but also contributes to sustainable water resource management practices.

Main applications of Aqualabo turbidity measurement solutions

Aqualabo’s advanced turbidity measurement solutions find multiple applications in critical sectors. Our NTU sensor is ideal for applications where a wide measuring range is required. These include municipal wastewater treatment, wastewater network assessment, industrial effluent monitoring, and surface water control. In all these applications, our sensor helps to efficiently manage treatments or provide real-time data critical to environmental protection. Meanwhile, the innovative LowTuS sensor is specifically designed for drinking water applications requiring precision and accuracy in the low range, in particular for monitoring the efficiency of filtration and treatment processes, as well as the turbidity of drinking water, vital for maintaining quality and guaranteeing public health.

Measurement principles used by our turbidity sensors.

Based on infrared scattering, our sensors provide accurate, consistent readings even in low ranges. The LowTuS sensor has an automatic cleaning feature to prevent false results and ensure effective turbidity monitoring. It incorporates an efficient debubbling system for highly accurate measurement of even the lowest values. The NTU sensor can be used for wider applications by direct immersion in the medium.

Why use and trust Aqualabo’s turbidity probes?

The flexibility of integration of our turbidity sensors via universal Modbus communication makes them the preferred choice for integration into an existing control or monitoring system. It is also possible to combine our probes with a fixed controller for local management, allowing the configuration of alarms or the implementation of regulations. Our sensors incorporate digital signal pre-processing to protect measurement reliability from interference, even in the most extreme conditions. Finally, the wide measuring ranges and innovative self-cleaning system are definite advantages.

Turbidity FAQs

Maintenance of a turbidity sensor is essential to ensure optimum performance. Clean the sensor regularly to remove deposits that can affect measurements. An automatic cleaning system, as offered with the LowTuS Premium version, or anti-fouling accessories such as the hydroclean for the NTU probe, can optimize cleaning frequency. Calibrate the sensor periodically with known turbidity standards. Ensure that the sensor is protected from physical shock. Record calibration data and perform periodic checks.

Absolutely. Our NTU probe, with its compact and lightweight design, is well-suited for both handheld and fixed unit applications. This adaptability ensures flexibility in measurements across diverse scenarios, making it an ideal choice for portable water quality monitoring.

The LowTuS sensor is equipped with special features, including debubbling and optional automatic cleaning systems. These features prevent interference from bubbles and deposits, ensuring accurate measurements even under difficult conditions. This design innovation increases the reliability of Aqualabo probes in providing accurate turbidity data for various applications.

The Modbus RS-485 and SDI-12 communication options provide seamless integration with a variety of devices, allowing for real-time data transmission. It also ensures reliable measurement by eliminating potential signal interference.
