The HQD® HQ430D Laboratory BOD Meter with LBOD101 optical sensor is an advanced solution for accurate biochemical oxygen demand (BOD) measurement in laboratory settings. It uses LDO (Luminescent Dissolved Oxygen) optical technology, eliminating the need for membrane and electrolyte replacement, simplifying maintenance, and improving measurement stability. The HQ430D delivers fast results with minimal operator intervention, supports automatic temperature compensation, and offers data storage capabilities. The package is suitable for wastewater, natural water, and drinking water analysis in environmental monitoring, industrial control, and research laboratories. Its robust design, large display, and user-friendly menu ensure comfortable operation and high measurement accuracy in compliance with international BOD testing standards
