BOQU has completely independent intellectual property rights for CODG-3000 automatic online COD analyzer. it's user Potassium dichromate principle and totally auto-measurement and unattended for a long time.
Main features:
1)Unique design makes this product have lower failure rate, lower maintenance, lower reagent consumption and higher cost performance than similar products.
2)Select valve component: Select reagent sampling timing, flexible channels, wide function, minimum dead volume, easy maintenance and long life.
3)Micro-metering component: Accurate metering of reagents through visible photoelectric system, which overcomes the quantitative error caused by wear of peristaltic pump tube; at the same time, it realizes accurate quantification of trace reagents, each dose is only 1 ml, which greatly reduces the reagent usage.
4)Sample Injection component: peristaltic pump suction in negative pressure, there is always an air buffer between the reagent and the pump tube, avoiding the corrosion of the pump tube; at the same time, the reagent mixing is more compact and flexible.
5)Sealed digestion component: high temperature and high pressure digestion system, speeding up the reaction process, overcoming the corrosion of equipment by corrosive gas volatilization of open system
6)Reagent tube: imported modified PTFE transparent hose, the diameter of the tube is more than 1.5mm, reducing the probability of water sample clogging

Value error: ≤±10%;
Measurement period:35minutes ~120miuntes according to the actual water sample
The digestion time:The digestion time is adjustable in 10min to 120miutes.
Sampling period:Time interval(55~9999min adjustable by yourself) and
Integral time measurement mode;
Calibration period: adjustable in 1~99days;
Maintenance period: Usually one time per month and 30 minutes each time
Output: 4~20mA( 2 ways) RS232,RS485;
Relay: 2 relays;
Ambient requirement: it should be indoor and temperature can be adjustable.
The recommend temperature is +5~28ºC;humidity≤90%(no dew);
Power:AC220±10% V,50±10% Hz,5 A;
Dimension size: Height 1450×Width510×Length 450 mm;
Data saved: the data can be saved when abnormal alarms and power off.
Display: touch screen and Command Input
Other:When Reset after abnormal alarm and power on after off,
the instrument automatically discharges residual reactants in the instrument and
automatically resumes working status.
