TL2300 Tungsten Lamp Turbidimeter
Principle of Operation
TL2300 and TL2350 Turbidimeters: The optical system is comprised of a tungsten-filament lamp, lenses and apertures to focus the light, a 90° detector, forward-scatter light detector, a backscatter detector (TL2350 only) and a transmitted-light detector. The instrument permits turbidity measurements at less than 40 NTU to be performed using only the 90° scattered-light detector or from 4000 NTU (TL2300) to 10000 NTU (TL2350) using the complete set of detectors (Ratio Measurement). With the Ratio Measurement on, the instrument’s microprocessor uses a mathematical calculation to ratio signal s from each detector.
Benefits
1.Improved and intuitive design
The TL23 Series’ large full color touch screen display and intuitive user interface accelerate setup, calibration and measurement. An easy interface and guided procedures give you confidence in your results.
2.A smart device for more reliable measurements
The TL23 Series ensures stable readings and accurate analysis by capturing turbidity readings once the device detects sample stability. This quality step removes subjectivity and the need for repeated measurements.
3.Easy to use. Easy to Be Right
The TL23 Series provides everything you need at your fingertips. With a USB port for easy data export, sample identification for traceability, and self-diagnostics for quality assurance, Hach® makes it easy to Be Right.
