UPW-BA506 Mercury-Free Safety BOD Analyzer

Product Overview
The UPW-BA506 Mercury-Free Safety BOD Analyzer is designed to measure biochemical oxygen demand (BOD) in water using a pressure-difference respirometric method. By monitoring pressure changes associated with oxygen consumption during microbial decomposition, the instrument calculates BOD concentrations and displays results directly, reducing the need for manual calculations.
Designed for routine water quality analysis, the UPW-BA506 measures up to six samples simultaneously and provides a selectable measurement range of 5–2000 mg/L. Its 7-inch color touchscreen, automatic data logging, built-in printer, and optional RS232/USB connectivity support convenient operation and data management. The mercury-free sensing method eliminates the need for mercury-based pressure measurement, improving operational safety.
The analyzer is suitable for environmental monitoring, petrochemical facilities, healthcare-related laboratories, educational institutions, and scientific research.

Key Features
• Mercury-Free Measurement: Uses a pressure-difference respirometric method without mercury-based sensing components, reducing mercury-related safety risks.
• Six-Sample Capacity: Supports simultaneous measurement of up to six samples for efficient laboratory workflows.
• Wide Measurement Range: Measures BOD concentrations from 5 to 2000 mg/L, with direct measurement possible for suitable samples within the specified range without dilution.
• Automatic Data Analysis: Calculates BOD concentration and generates measurement curves for straightforward result interpretation.
• Flexible Test Scheduling: Supports test periods from 5 to 30 days and selectable data recording intervals from 5 minutes to 24 hours.
• Touchscreen Operation: Features a 7-inch color touchscreen for parameter configuration, real-time monitoring, and historical data review.
• Automatic Data Protection: Saves measurement records automatically and supports data retention during unexpected power interruptions, with testing resuming after power restoration.
• Integrated Printing and Connectivity: Includes a built-in microprinter and optional RS232/USB data transfer for result documentation and computer-based data management.

Working Principle
The UPW-BA506 uses a pressure-difference respirometric method to determine biochemical oxygen demand. During the test, microorganisms in the water sample consume dissolved oxygen while decomposing biodegradable organic matter. The associated gas-pressure changes within the measurement system are monitored and used to calculate oxygen consumption.
The instrument processes the measurement signals and converts them into BOD concentration values. It automatically records test data, generates measurement curves, and displays results on the touchscreen. Users can configure the measurement period and data recording interval according to their testing requirements.
The method avoids mercury-based pressure sensing. Appropriate sample preparation, temperature control, and method-specific procedures are necessary to obtain reliable results.

Applicable Standards
The supplied product information does not identify specific standards or regulatory approvals for the UPW-BA506.
Before using the instrument for compliance testing, confirm whether its pressure-difference respirometric method and operating procedure are accepted under the applicable local regulations or laboratory method. Results should not automatically be considered interchangeable with dilution-method BOD₅ results without method validation.

Comparison

Comparison Item	UPW-BA506 Mercury-Free BOD Analyzer	Conventional Dilution-Method BOD₅ Testing
Measurement Principle	Pressure-difference respirometric method	Dissolved oxygen measurement before and after incubation
Mercury Use	Mercury-free sensing method	Depends on the equipment used; mercury is not inherently required
Sample Capacity	Up to 6 samples simultaneously	Depends on the number of incubation bottles and available equipment
Result Calculation	Automatic calculation and display	Typically requires initial and final dissolved oxygen values and calculation
Data Recording	Automatic recording with configurable intervals	Depends on the measurement and recording system
Incubation Temperature	20 ± 1°C	Commonly 20 ± 1°C for standard BOD₅ testing
Test Duration	Adjustable from 5 to 30 days	Commonly 5 days for BOD₅
Data Output	Touchscreen, built-in printer, optional computer transfer	Depends on the dissolved oxygen meter and laboratory workflow

The UPW-BA506 is suitable for laboratories seeking automated respirometric BOD measurement and continuous data recording. Conventional dilution-method testing may be preferable when a particular regulatory method explicitly requires that procedure. Selection should be based on the required standard, sample characteristics, reporting requirements, and laboratory workflow.
