CODA-500 online automatic monitoring instrument for permanganate index (CODMn)

application area
Determination of permanganate index (CODMn) in surface water and drinking water sources

Functional Features
1) Save reagents: HORIBA's proprietary reagent measurement method enables precise measurement and reduces the amount of reagents required for CODMn automatic monitoring. It requires only 1/10 of the amount of reagents used in traditional systems, which can reduce operating costs and make maintenance easier.
2) Environmental Protection: As a direct heating system is used, cooling water is not allowed. When the system is running, it can reduce power consumption by 50%, which helps alleviate environmental burden.
3) Simple: The reality panel of this system is a color LCD touch screen, which makes operation easier; This system can also provide a wide range of interface options (RS-232C/RS-485/USB/Modbus) and support the use of multiple languages.
4) Automatic alarm, can be stored for 1 month or longer (internal)/connected to external storage via USB.
