Lab Expo Benchtop Turbidity Meter 25-BTM104 measures water clarity using the 90° scattered light principle with an infrared-emitting diode at 850 nm and silicon photodiode detector. It covers two ranges: 0–100 NTU and 100–1,000 NTU, with a minimum readout of 0.01 NTU and error value of ±6% (±2% F.S.). Zero drift is ±0.5% F.S., calibration uses seven points, and it stores up to 20 data sets. Suitable for quality control in beverage, pharmaceutical, environmental testing and research labs requiring precise turbidity assessment under ISO-aligned conditions.
