Description
The Lovibond® TB 211 IR is a compact, portable turbidity meter designed for fast and reliable on-site water analysis. It uses an infrared LED at 860 nm and a 90° nephelometric measurement principle in accordance with EN ISO 7027. Its wide 0.01–1100 NTU measuring range makes it suitable for applications ranging from drinking-water testing to wastewater monitoring.
The infrared measurement system also enables testing of both coloured and colourless water samples. Results can be transferred to a computer through the integrated Micro-USB interface, while internal memory stores up to 125 measurement datasets.
