Designed for portability and durability, the waterproof CHEMetrics Turbidity Meter (Cat. No. I-1300) is ideal for monitoring turbidity in chemical, food, and industrial applications.  The microprocessor-based turbidity meter uses an infrared LED light source and delivers unprecedented repeatability and accuracy while offering resolution as low as 0.01 NTU.  This light-weight meter is a valuable analytical tool for field-testing and quality control.

Method of Operation.

The turbidity meter is equipped with an infrared LED as its source of light and meets all testing requirements of ISO-7027 (DIN EN 27027) method (Nephelometric Turbidity Units).  The wavelength peaks at 850 nm, which provides the required intensity of diffused light even in samples with low turbidity values and also reduces interference from any colors.

The meter determines the sample turbidity level and automatically adjusts to the appropriate measurement range (0-1000 NTU), eliminating guesswork.  Pressing the CAL button initiates the quick and simple calibration procedure.  The instrument automatically prompts the user for the next calibration standard.  The meter comes with four primary calibration standards (0.02, 20.0, 100, and 800 NTU).  The meter also comes with three borosilicate sample cuvettes with light-shield caps.
