Digital RS485 Interface Modbus COD Controller For Surface Water Monitoring

Digital RS485 Interface Modbus COD Controller For Surface Water Monitoring

The COD analyzer uses UV254 nanometer ultraviolet absorption method to measure, and the measurement process does not require consumables. In addition, another compensation light source can effectively eliminate the influence of turbidity and chromaticity, and achieve more stable and reliable measurement.
