product details


Principle:

QCOD-2E Chemical Oxygen Demand Analyzer is designed by the principle of catalytic and sealed digestion. Sample is sealed digested by special oxidant and composite catalyst for 10min at 165℃, Potassium dichromate is reduced to trivalent chromium by organic matters in water. The amount of trivalent chromium is measured at 610nm, and then converts it to the consumption of Oxygen concentration. The instrument adopts advanced cold light source, narrow-band wavelength interference and microcomputer automatic data processing, and directly shows the COD (mg/L) concentration of samples. It is widely used in environmental monitoring department, wastewater treatment, universities and research institutes, etc.
Digester: 200mm×240mm×190mm

11. Weight: <3kg




Features:

a) Cold light and monochromatic light source, excellent optical stability.

b) PID automatic temperature control and high precision.

c) Two-line LCD, easy to operate.

d) Digester and colorimeter (including main unit) are separated, avoid temperature interfere with the optical part.

e) High efficiency, 20 water samples can be digested each time and only needs 20 minutes.

f) 5 working curves in memory which can be calibrated by users; 225 sets of data with time tag can be stored.

g) Data protection when Power failure.
