Lovibond launch TB350 to provide laboratory level accuracy in a portable device

Lovibond has launched the TB350 for turbidity measurements, which they say can provide results with the accuracy of laboratory instruments using a portable device and can eliminate some of the challenges of turbidity measurements, such as inaccuracies due to stray light, complicated handling and time-consuming calibration.

The device uses new patented sensor technology, called the Multipath 90° BLAC® which Lovibond claim makes the TB350 able to deliver the highest accuracy in the lowest turbidity range from 0.01 NTU and also maintains precision in the highest turbidity range up to 4,000 NTU.

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

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

Lovibond believe the TB350 makes calibration and verification procedures, which are otherwise quite complicated in turbidity measurement, easier than before. Formazin-based T-CAL® primary solutions are sealed in airtight vials and can be used immediately, ensuring possible errors due to user preparation or dilution of standards can be avoided as well as users avoiding contact with harmful chemicals.

The new TB350, available as an infrared or white light version, is compliant with valid ISO 7027 and US EPA (pending) regulations and standards.
