In colorimetric mode, users can select between factory preprogrammed calibration or calibrating the meter on their own, and measure either concentration or relative absorbance of the sample. Up to 25 measured samples can be stored in memory together with time and date. AA Batteries and instruction manual. LED Light Source LP 2000 is the only bench turbidity meter on the market with this superior feature. Accuracy Unsurpassed accuracy with 0.5 FTU through an extensive range.
Calibration is automatic, quick and simple.
Two calibration standards with fixed values of 0 and 10 FTU are automatically recognized by the microprocessor. LP 2000 uses the infrared beam and the 90 sensor method to measure turbidity since it is less sensitive to color as opposed to the filter system. LP 2000 is the only turbidity meter equipped with an infrared LED as source of light. The infrared LED has a long life, unlike standard lamps, and more importantly, it maintains constant emission for the entire life of the instrument. The wavelength peaks at 890 nm, which ensures maximum intensity of diffused light even in samples with low turbidity values, and also reduces the interference from any colors.
