Full Product Description
Biochemical Oxygen Demand (BOD) serves as the primary environmental index for assessing organic pollutant load and evaluating municipal/industrial wastewater biodegradation kinetics. The Lovibond® BD 600 and BD 600 GLP respirometric sensor systems provide simultaneous, automated determination of up to 6 water samples. Operating on the manometric principle, integrated piezoresistive electronic pressure sensors continuously correlate microbial oxygen uptake to gas-phase pressure drops within constant-volume sample vessels, delivering a 100% mercury-free testing environment.
Available Model Variants within the Product Family:
1. Lovibond BD 600 (Standard Analytical BOD Instrument):
• Digestion Periods: User-selectable measurement intervals from 1 to 28 days (optimized for standard BOD₅ and BOD₇ compliance).
• Data Storage: Up to 744 measurement records automatically logged (hourly during day 1, bi-hourly during day 2, and once daily from day 3 to 28).
• On-Screen Graphic Visualization: Backlit graphic LCD (128 x 240 pixels, 45 x 84 mm) plots real-time BOD development curves directly on the instrument display without requiring PC connection.
• Intelligent Autostart Feature: Automatically delays measurement initiation until samples equilibrate thermally within the incubation chamber (15°C to 21°C), eliminating thermal expansion pressure artifacts.
• Hybrid Power Supply: Operates on 3 x C-size alkaline batteries or external 100–240 V mains via a shared Y-cable connected to the stirring base.
2. Lovibond BD 600 GLP (Advanced GLP & OECD Biodegradability System):
• Regulatory Biodegradability Testing: Specifically configured for chemical registration and detergent biodegradability testing in strict adherence to OECD 301 F, OECD 301 C, and OECD 302 C guidelines.
• Extended Measurement Timeframes: Configurable for 5, 28, 60, and 90-day extended biodegradability assessments.
• Massive 1 GB Memory Storage: Equipped with an industrial SD card storing up to 50,000 measurements for complete traceability and Good Laboratory Practice (GLP) data integrity.
• Enhanced Logging Intervals: Logs measurements every 2 hours (5-day cycle), every 12 hours (28-day cycle), or every 24–48 hours (60 to 90-day cycles).
• Power Supply: 100 – 240 V, 50/60 Hz universal mains.
Inductive Stirring System & Complete Delivery Package:
• Non-Wearing Inductive Stirring: Utilizes a non-mechanical, inductive magnetic drive to synchronously rotate stir bars across all 6 bottles, eliminating mechanical motor belt degradation and ensuring consistent gas-liquid mass transfer.
• Flexible Measuring Ranges: User-selectable ranges: 0–40, 0–80, 0–200, 0–400, 0–800, 0–2,000, and 0–4,000 mg/l O₂ without laborious preliminary sample dilutions.
• Scope of Delivery: Complete turnkey system including base unit with 6 electronic sensor heads, 6 amber glass sample bottles, 6-place inductive stirring rack, overflow measuring flasks for precise sample metering, nitrification inhibitor (ATH), and potassium hydroxide (KOH) CO₂ absorbent flakes.
