Lovibond TurbiDirect Infrared Turbidity Meter to EN ISO 7027

Lovibond TurbiDirect Infrared Turbidity Meter

The Lovibond TurbiDirect from the Tintometer Group measures turbidity according to EN ISO 7027 by the nephelometric method, detecting the light scattered at 90°. Its infrared light source (IR-LED, 860 nm) permits measurement of both coloured and colour-free samples.

Automatic measuring range detection (Autorange) gives direct turbidity readings from 0.01 to 1100 NTU, with an accuracy of ± 2 % of reading or 0.01 NTU up to 500 NTU. Overall range adjustment is carried out with the T-CAL turbidity standard set, and the waterproof sample chamber and housing make the instrument suitable for both laboratory and mobile use.

A large graphic display, a choice of several operating languages and user-friendly instructions make the meter very easy to use. Up to 1000 data sets can be stored with real-time clock stamping and transferred to a printer or PC through the RS232 interface. Software updates, for example new languages, can be downloaded free of charge from the manufacturer's website.
