Abstract
In this study, we have developed a portable light-scattering turbidimeter by combining an MPU(microprocessing unit, ADuC-848) and an AD/DC converter. In short, the developed device has a simplified circuit structure and showed improved performance. The calibration curve for NTUmanual vs NTUsensor was found to be linear over the range of 0 NTU to 40 NTU. Calibration sensitivity (slope) was and was 0.9996. In addition,the calibration curve for NTUmanual vs NTUsensor was linear over the range of 0 NTU to 400 NTU. Calibration sensitivity is and is 0.9999.
Key Words: Turbidimeter, Enviromental water samples, MCU(ADuC-848)
