The Apera TN480 (AI486) is a portable, ISO 7027-compliant turbidity meter designed to measure suspended particles in water and other aqueous solutions. Its 860 nm infrared LED and 90° nephelometric measurement method help minimize interference from naturally colored samples, making it suitable for testing nutrient solutions, irrigation water, and filtration output. The meter includes five-point calibration and a GLP data logger for traceable water-quality monitoring.
