Product Overview
The 200 mg/L COD calibration standard is a high-precision liquid solution formulated for accurate chemical oxygen demand (COD) measurements in laboratory settings. Designed with analytical-grade purity, this standard ensures consistent and reliable calibration of COD meters, spectrometers, and other testing instruments. Its stable formulation minimizes degradation over time, providing long-term accuracy for water quality analysis, wastewater treatment monitoring, and environmental testing. The solution is pre-diluted to 200 mg/L concentration, eliminating the need for manual preparation and reducing potential errors. Compatible with most standard COD testing protocols, this calibration standard meets international quality benchmarks, making it ideal for research, industrial, and educational applications where precision is critical. The liquid form allows for easy handling and dispensing, while the analytical grade guarantees minimal interference from contaminants. Whether used for routine instrument maintenance or quality control checks, this COD standard delivers reproducible results, ensuring compliance with regulatory requirements and laboratory best practices.
FAQs
