Sažetak
A low-cost turbidimeter, colorimeter, and nephelometer (TCN) multipurpose instrument applicable for undergraduate, graduate, and research laboratories is demonstrated within this work. The instrument relies on simple and robust electronics while using a PC sound card as an analog-to-digital converter. The performance of the instrument was evaluated by measuring sulfate content in water. The analyses were compared to a research-grade UV/vis spectrophotometer. Despite its simplicity, the instrument was demonstrated to be an interesting and viable means for hands- on approach teaching in student laboratories.
