Model HH-6 COD Analyzer------serial products of environmental protection analysis instrument Model HH-6 COD (chemical oxygen demand) Analyzer is designed by the optical analysis principle to give a precise COD measurement. In this method, the catalytic and sealing digestion technique, the cold light source, the narrow-band interference technique and the microcomputer is used. And by these, a COD value can be measured rapidly and exactly, and displayed in the LCD display directly; especially, in the measurement process, the digestion step can complete only within 10 minutes. This instrument is widely used by environment monitoring departments, sewage disposal works, mineral enterprises, and laboratories of science and research academy, etc. Specifications: Temperature controlling system: 165 ± 1.5 oC Catalytic and sealing digestion technique Digestion time: 10 min Cl- ion interference range: Cl-1200 mg/L Detection limit: 5 mg/L Measuring range: 5 mg/L to 2000 mg/L Error: 5 mg/L to 100 mg/L, absolute error: ≤ ±5 mg/L 100 mg/L to 2000 mg/L, relative error: ≤ ± 5% Repeatability: accord with standard deviation ≤ ± 3% Optical stability: A ≤ 0.002/20 min Sample amount: 20 pcs water sample Dimension: 420mm×350mm×175mm Power: ≤ 500 W Characteristics: Temperature and time can be set by yourself Automatically controlling temperature and time Cold light source Narrow-band interference technique Automatic data processing Automatic zero adjustment Automatic protection when power off Five regression curves can be dispatched any time Print various parameters
