The infrared LED on the Portable Turbidity Meter, produces the required intensity of diffused light in samples with low turbidity, and reduces interference from colors. To ensure accurate calibration schedules, the meter also has a unique GLP (Good Laboratory Practice) feature that automatically stores and retrieves the last calibration data with time and date. For best field accuracy, the meter measures from 0–50 FTU in steps of 1⁄100 FTU, that is 10 times better than comparable models that measure 10–50 in tenths.
Features an easy-to-use four-button keypad, automatic troubleshooting functions and auto shut-off after 5 mins.
Range: 0.00–50.00 FTU/50–1000 FTU, 1 FTU (Formazine Turbidity Unit) = 1 NTU (Nephelometric Turbidity Unit).
Resolution: 0.01 FTU/1 FTU. Accuracy: ±0.5 FTU or ±5%.
Light Detector: Silicon Photocell.
