COD100 Laboratory COD Analyzer — Dual‑Range & EPA/ISO Compliant
OVERVIEW
The COD100 Laboratory COD Analyzer is a compact and reliable instrument designed for accurate chemical oxygen demand (COD) testing in water samples. It complies with EPA 410.4 and ISO 15705:2002 standards, making it ideal for use in environmental labs, wastewater treatment facilities, and industrial water testing.
Equipped with an LCD display and two LED light sources, the COD100 supports dual-range COD analysis: low range 0–150 mg/L and high range 0–1500 mg/L. Its two-point calibration system ensures consistent accuracy, with a basic error margin of ±8% and repeatability within 3%.
The analyzer includes a COD100R reactor, capable of digesting up to 21 samples simultaneously, with adjustable temperature (100–165°C) and time settings (0–120 minutes). Additional features include 200-set GLP data storage, USB interface, and sealed reflux digestion for safety and efficiency. Compact dimensions: 315 × 225 × 100 mm, lightweight 2 kg.
COD100 Laboratory COD Analyzer – dual-range COD (0‑150 / 0‑1500 mg/L), ±8% accuracy, ≤3% repeatability, 200‑set GLP data storage with timestamps, USB interface, sealed reflux digestion method.
