Chemical Oxygen Demand Tube Test System
The Lovibond MD 100 COD Meter is a dedicated, single-parameter instrument designed solely for accurate Chemical Oxygen Demand analysis using Lovibond VARIO COD tube reagents. It delivers fast, reproducible COD test results for compliance reporting, pretreatment monitoring, and wastewater process optimization — without the added cost or complexity of multi-parameter colorimeters.
Dedicated COD Instrument
Designed specifically for COD tube digestion testing — no unused menus or multi-parameter distractions.
EPA-Reportable COD Analysis
Works with Lovibond VARIO COD reagents for low, medium, and high ranges. Mercury-free reagent options are available.
Rugged, Waterproof IP68 Housing
Survives field environments and accidental immersion up to 1 hour at 0.1 m. The unit floats if dropped in water.
Reliable Optical System
LED and interference filter design ensures stable, accurate, and repeatable readings.
One-Time Zero Function
Zero a single blank and run all tests from that sample without re-zeroing.
Automatic Data Storage
Stores the last 16 results with time and date stamp. Download records using the optional IRiM interface.
User Calibration Mode
Supports one-point calibration and reading display in ABS or %T.
Factory-Loaded Curve Library
Up to 14 COD calibration curves installed and ready to use.
Ergonomic Design
Comfortable to hold in the field and stable on benchtops with integrated rubber foot pads.
Two-Year Warranty
Confidence backed by Lovibond’s industry-proven reliability.

Many facilities evaluating COD testing equipment also consider models from Hach, Thermo Scientific, LaMotte, Hanna, Chemetrics, and other multi-parameter platforms. The MD 100 offers a simpler, more focused approach for operators who only need COD.
Hach DR instruments are multi-parameter colorimeters and spectrophotometers. The MD 100 is dedicated to COD only, making it easier to operate, quicker to train, and typically more cost-effective. It also provides IP68 waterproof protection and floating capability, which most DR instruments do not.
Thermo units offer broader photometry menus but often cost more and involve additional configuration steps. The MD 100 boots directly into COD testing, with built-in test curves and one-time zeroing for fast workflow.
LaMotte systems are popular for classrooms and basic lab testing. The MD 100 is better suited to industrial and municipal wastewater operations requiring reporting alignment, data logging, calibration, and tube-based digestion ranges.
Ampule-based COD kits are simple for screening but lack official EPA alignment, timestamped result storage, calibration capability, and digital reporting functions. Facilities that need traceable, defensible COD records often prefer the MD 100.
Multi-parameter platforms add cost and complexity when COD is the only required analysis. By focusing on COD alone, the MD 100 provides:
Lower overall acquisition cost
Faster testing workflow
Easier operator training
Reduced maintenance
A more rugged field-ready housing
Municipal wastewater treatment
Industrial pretreatment monitoring
Food and beverage processing
Stormwater and runoff analysis
Process optimization and load balancing
Compliance and discharge reporting
Environmental lab work
University research and instruction
Dedicated, COD-only platform
EPA-recognized reagent options
Durable IP68 waterproof housing
One-time zeroing for fast batch testing
Built-in calibration curves
Internal result storage with timestamps
Mercury-free reagent availability
Compact size for field or lab use
Lower cost of ownership compared to most multi-parameter instruments
