The Portable COD (Chemical Oxygen Demand) Analyzer integrates a portable COD meter with a COD sensor that employs the latest spectroscopic technology. Utilizing the 254nm spectral absorption coefficient (SAC254), it measures soluble organic matter in water by detecting ultraviolet light absorption. This allows for accurate estimation of COD and BOD values under specific conditions. Designed for continuous, reagent-free monitoring, this instrument offers reliable, real-time analysis ideal for environmental and water quality professionals seeking efficient organic matter assessment. IP67-rated protection for reliable performance in harsh environments. 3.5-inch color display with an intuitive menu for easy and efficient operation. Ergonomic curved design with a rubberized non-slip hand strap to ensure secure grip, even in wet conditions. 8GB of internal data storage with USB connectivity for seamless data export Built-in rechargeable battery charges via USB port. Automatic sensor recognition with adaptive reading interface for streamlined use. Sensor parameterization and calibration capabilities for precise and customizable measurements. Applications On-site, portable monitoring of organic matter load and water quality of plant inflow and outflow during sewage treatment. On-site, portable monitoring of surface water, industrial sewage pipe discharge, and fishery sewage discharge.
