Revolutionising turbidity measurement with precision and ease

TB350 Turbidity Meter from Lovibond®

The everyday challenges of turbidity measurement, such as inaccuracies due to stray light, complicated handling, and time-consuming calibration, are now eliminated with the Lovibond® TB350. The TB350 is the most advanced portable turbidimeter on the market with brand-new technology, unprecedented measuring range and unsurpassed accuracy.

Multipath 90° BLAC® is the new, patented sensor technology, making the TB350 the most versatile turbidimeter combining laboratory accuracy in a portable instrument. The new technology ensures the highest accuracy is guaranteed in the lower turbidity range from 0.01NTU and maintains the outstanding precision level in the highest turbidity range up to 4,000 NTU.

The recently developed optical system works with two ingeniously arranged 90° detectors and thus ensures a purely nephelometric measuring principle. During the turbidity measurement, two different path lengths of the incident light beam through the sample are cleverly exploited. Various particle sizes and shapes are detected with the highest measurement accuracy even where the particle size distribution deviates from the calibration standard.

The novel BLAC® technology stands for Backscattered Light Absorbing Cavity. The light-absorbing trap almost eliminates unwanted stray light and provides extremely accurate results for low turbidity down to 0.01NTU.

The new sensor technology was specifically designed by a team of world-renowned turbidity experts to solve common user problems in turbidity measurement. With intuitive colour touch screen and straightforward data management protocols ensure easy handling. A customised measuring mode for fast-settling particles, the 'Fast Settling Mode', complements the outstanding instrument performance increasing the accuracy of the turbidity reading for large and heavy particles from 20 NTU, but especially in the high measuring range of up to 4,000 NTU.

The TB350 makes calibration and verification procedures, which are otherwise quite complicated in turbidity measurement, easier than ever before. Formazin-based T-CAL® primary solutions are safely sealed in airtight vials and can be used immediately.
