Featuring the sensor technology Multipath 90° BLAC, the optical system is engineered with dual detectors to deliver a ratio reading which mitigates common measurement stability issues.BLAC: The darker the better Experts solved two fundamental problems in turbidity measuring in a patented and unprecedented way.The sophisticated arrangement of the two detectors allows the analysis of low and high turbidity samples with unsurpassed accuracy over the complete measuring range up to 4,000 NTU.The angle of detection stays at 90° over the entire range. This ensures consistent results at any time, regard-less of the size and shape of the turbidity-causing particles.The BLAC® technology stands for: Backscattered Light Absorbing Cavity.The trap (BLAC®) eliminates stray light perfectly and provides extremely accurate results for low turbidity down to 0.01 NTU.Touchscreen interface & function application The intuitive full-colored touchscreen interface makes it easy to perform procedures and interpret results. With function applications, you can navigate between settings and performing that function efficiently. This user interface eliminates common frustrations and errors found with competitive products and guarantees outstanding operating convenience with animated procedures. There are 3 reading modes: single, signal averaging, fast-settling.Data logging & USB The data logging capabilities allow you to record the testing location, operator's identification, time and date along with the measurement. Stored data can be transferred to a computer via USB.Competence in Turbidity At Lovibond®, Lovibond look out for the little things that make a big difference. On the surface, turbidity analysis is a simple measurement. However, there are many factors that can affect the accuracy of readings or the dependability of an instrument. Lovibond obsess about turbidity measurement so you don't have to. Team of globally recognised turbidity experts work to anticipate and solve operators' struggles with turbidity measurement.
