The Turbidity Detector is a high-performance, portable instrument engineered for accurate and reliable measurement of water clarity and suspended particle concentration. Utilizing the proven infrared light scattering method in full compliance with ISO7027 standards, this device ensures exceptional accuracy across a broad measuring range of 0 to 1100 NTU. Its sophisticated optical system, featuring an 850nm infrared LED and a silicon photoelectric receiver, minimizes color interference and delivers highly repeatable results with a stray light level of less than 0.02 NTU. Designed for versatility, this Turbidity Detector supports single measurement mode for quick, automatic endpoint locking and continuous measurement mode for profiling or sample bottle matching, making it an indispensable tool for both field surveys and process control.
This advanced Turbidity Detector is built for the demands of environmental and industrial applications, including wastewater treatment, drinking water analysis, aquaculture, and surface water monitoring in rivers and lakes. The instrument offers flexible 2 to 5-point calibration using Formazin standards and allows users to select from four measurement units (NTU, EBC, ASBC). With an expanded memory capable of storing 100 data sets, a USB communication interface for easy data transfer, and automatic power management, it combines laboratory-grade precision with field-portable convenience. Weighing only 300 grams and powered by AA batteries or a DC adapter, this robust and user-friendly device empowers professionals to conduct critical water quality assessments anywhere, anytime.
