COD Analyzer Features
The digestion device is separated from the COD analyzer and does not affect the measurement accuracy. Temperature PID automatically controls temperature and timing.
High-performance ultra-low-power 16-bit microcontroller with instrument standby time of more than 6 months.
The operation saves time and the COD digestion takes only 15 minutes.
Cold light source, narrow-band interference optical system, good optical stability.
Data power-off protection.
Each of the COD standard curve 50 and 500 measured values (including the COD value, absorbance value and light transmittance of the year, month, day, hour, minute and second with time stamp) can be saved.
With a USB port, you can connect to a computer for record reading or print stored data.
The mainframe casing is molded with ABS material and IP65 design, which is waterproof and dustproof.
5 ~ 2000mg / L, exceeding the dilution test.
