Shanghai Jingqi Economical COD Analyzer (Including Digester) COD-5, Shanghai Jingqi Instrument Co., Ltd. (CAT#: STEM-AI-0925-YJL)

Shanghai Jingqi Economical COD Analyzer (Including Digester) COD-5, model COD-5 is manufactured by Shanghai Jingqi Instrument Co., Ltd.
The product is digested using sealed catalytic digestion followed by colorimetric measurement. The instrument adopts advanced cold light source, narrow-band interference technology and microcomputer to process data automatically, and directly displays the COD (mg/L) value of the sample. The instrument is widely used in environmental monitoring, sewage treatment, universities, research institutes and other departments.

Indication error: ≤±8%
Repeatability: ≤3%
Anti-chlorine interference: ≤2000mg/L
Temperature control system: room temperature ~ 180°C can be set, digestion temperature is 165°C
Temperature control accuracy: ±0.5°C
Temperature control time: 1~999min adjustable
Digestion time: 15min
Optical stability: The absorbance value of the instrument drifts less than 0.002A within 20 minutes
Batch capacity: 12 water samples
Dimensions: Host: 240mm×205mm×170mm
Digestion instrument: 240mm×107mm×170mm
Weight: Host 3kg Digester 4kg
Power consumption: <500W
Normal use conditions:
⑴ Ambient temperature: 5～40℃ ⑵ Relative humidity: ≤85%
⑶ Power supply: AC(220±22)V; (50±0.5)Hz
⑷ No significant vibration and electromagnetic interference, avoid direct sunlight

The measuring instrument is separated from the digestion instrument, which does not affect the stability of the optical system
The measuring instrument is a cold light source, a narrow-band interference optical system, and has good optical stability
LCD large-screen liquid crystal display in Chinese, easy to operate and intuitive
Digestion instrument temperature PID automatic temperature control, timing, high precision
The operation is simple and time-saving. Digestion colorimetric without changing tubes
Digestion temperature and time can be set steplessly for other purposes
10 standard curves and 500 measured values can be saved, and will not be lost when power off
