Laboratory & Field COD Analyzer for Rapid Water Quality Assessment

For environmental engineers, laboratory analysts, and industrial wastewater managers, rapid, reliable, and versatile COD measurement is essential for regulatory compliance, process control, and environmental monitoring.

The Instrava COD Analyzer provides fast detection of COD across 20–10,000 mg/L, with direct concentration readout and flexible measurement modes for both φ16mm tubes and 30mm cuvettes. The high-definition 3.5-inch OLED display and intuitive dial-style UI make operation simple, while the included LH-A109 9-hole digestion unit enables precise, reproducible sample preparation. Portable, lightweight, and durable, the instrument is designed to handle both field and laboratory workflows.
