The Hach Model 2100A Turbidimeter is a laboratory nephelometer calibrated for measuring turbidity in colorless liquids. It is suitable for a broad range of turbidity measurement with ranges of 0-0.2, 0-.1.0, 0-10, 0-100, and 0-1000 Nephelometric Turbidity Units (NTU).
Accuracy:Within ±2% of full scale
Reproducibility:Within ±2% of full scale
Sensitivity:Better than ±0.5% of full scale
Standardization:Turbid solutions with known turbidity values
Stray Light:Less than 0.04 NTU equivalent on low ranges, Less than 0.5 NTU equivalent on 0-100 and 0-1000 ranges
Dark Current:Less than 1.0% of full scale
Voltage Stability:No change in specification from 95-135 Volts or 190-270 Volts
