Project Description

Portable COD Analyzer

The portable COD analyzer, with high precision measurement capability, low system maintenance, accurate optical metrology system, automatic calibration and cleaning function. Suitable for surface water, surface water, sewage.

COD measuring instrument (including digestion instrument)

  • Battery power, handheld portable design

  • Customize the Chinese and English display of the instrument according to the customer’s needs

  • With 4-hole digestor

  • Suitable for field use and field use

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.
