Introduction
The HI97750 Potassium/Potassium Oxide Portable Photometer is an instrument used to measure potassium oxide (KâO) content in water. Potassium oxide is a common inorganic compound with an important role in agriculture and soil science, often used as a source of potassium in fertilizers. Commonly used in soil and agricultural product analysis to assess soil fertility and crop nutritional status. In addition, in industrial production processes, it may also be used to monitor the potassium oxide content in wastewater.
The HI97750 Potassium/Potassium Oxide Portable Photometer meets IP67 waterproof standards and features an innovative optical system design that provides excellent accuracy, repeatability and time required to make measurements. The CAL CheckTM feature allows performance verification of the instrument using NIST traceable standards. and calibration, multiple measurement methods, built-in reaction timer to ensure consistent results between sample measurements and users, Good Laboratory Practice (GLP) display of date and time of last user calibration, battery status indicator light and automatic power-off setting.
