BOD tester BK-BOD series

laboratoryfor environmental analysisfor water analysis

Introduction
Brand: BIOBASE. The BK-BOD series (BK-BOD804, BK-BOD806, BK-BOD804S, BK-BOD806S) is designed to measure biochemical oxygen demand (BOD) in water and wastewater. Models support independent operation per culture bottle and continuous measurement up to 5 days, suitable for environmental laboratories, wastewater treatment monitoring and industrial effluent control.

Key features

• Mercury-free differential pressure measurement method for safe experimental handling and direct BOD concentration output.
• Independent color LCD for each unit; S models include a 5-inch color touch screen and secondary 1.5-inch color LCD.
• Independent operation of each culture bottle with individual result display and large-capacity lithium battery options for single or simultaneous charging.
• Wide measurement range with 10 segmented ranges; results displayed directly without conversion and can be printed automatically.
• Automatic generation of color data charts and automatic data logging for real-time access to current and historical results.
• Low power consumption and compact footprint for laboratory or on-site deployment.
