Turbidity Meter LMTB200 is a precision laboratory instrument designed for accurate turbidity and total suspended solids (TSS) measurement in water and wastewater analysis applications. The system combines advanced optical detection with multi-point calibration capability to deliver stable and reliable turbidity measurement results.
The instrument supports turbidity measurement from 1 to 2000 NTU with selectable turbidity units including NTU, FNU, EBC, and ASBC. A built-in TSS conversion mode enables accurate suspended solids analysis for industrial and environmental applications.
LMTB200 features a 4.5-inch TFT display with user-friendly menu navigation and operational guidance for simplified testing procedures. The system supports 2 to 7-point calibration using Formazin standards to improve measurement accuracy across different turbidity ranges.
An infrared-emitting diode operating at 850 nm combined with a silicon photodiode detector ensures stable optical performance with low stray light interference. Continuous measurement mode allows indexing and matching of sample vials for improved repeatability.
The meter includes password protection, hold functionality, automatic reset options, and internal memory capable of storing up to 200 data sets for laboratory record management and traceability.
LMTB200 is suitable for industrial wastewater plants, municipal water treatment facilities, environmental laboratories, food and beverage testing, academic research, and industrial process monitoring applications.
