The CODA-500 is a CODMN monitor that fully automates JIS (Japanese Industrial Standards)-based measurement methods.
- Uses only 1/10 the reagent of the existing systems
Newly developed dispensing and quantification device enable the CODA-500 to maintain measurement accuracy while using only 1/10 the quantity of reagent required. A reagent delivery service also eliminates the need for time-consuming reagent preparation. This reduces the time and trouble involved in reagent replacement and cuts running costs in half.
- Touch panel LCD makes operation easier
The use of a color LCD with a touch panel makes operation intuitive, and lowe power consumption reduces environmental load. These and other functions attuned to the times will enable the system to meet future water quality management needs.
- Cuts power consumption in half
- Direct heating method requires no cooling water
- Full range of interface option (RS-232C, RS-485, USB, and Modbus)
