The principle of measuring turbidity is that the turbidity value is measured by measuring the intensity of the transmitted light by measuring the intensity of the transmitted light caused by the incident light emitted by the light source and the light scattering caused by suspended solids in the solution.
The turbidity measurement is in accordance with ISO7027 and EPA Method 1801 and standard method 2130B, CE certified (EN 5008-1 and EN 50082-1), according to the user's measurement requirements to facilitate the replacement of light source (ISO7027 is 890nm infrared light, EPA1801 for white light) The instrument's optical system is automatically adjusted, eliminating the need for frequent light calibration.
The low detection limit of the instrument determines the interference light. Both instruments have very low interference light and provide exceptional results even for low turbidity measurements. The LED light source is in line with the European ISO7027 or US epa 180.1. Tungsten light source, and select the required light source according to the measurement parameters you need. For samples containing tiny particles, tungsten lamps should be selected because of the shorter wavelength, higher sensitivity and satisfactory accuracy at low range turbidity (<1ntu).
The optical system has an automatic adjustment function, eliminating the need for frequent calibration. The backlight screen adopts a user-friendly interface and displays instructions** to guide users through various routine operations. Adopt Ti.The automatic system can record the operation time, location and other specific operating environment information.
The excellent GLP function provides users with comprehensive GLP information including calibration time and date and calibration point, the instrument can store 200 sets of data, and can be connected to a computer through USB or RS232 interface for data transmission and analysis processing.
Professionally measure turbidity with a measurement range of 000 to 9.99, 10.0 to 99.9 and 100 to 1000 NTU automatic range changeover for different water quality, with a choice of 2-, 3- or 4-point turbidity correction or custom numerical calibration to ensure consistency and accuracy of measurements. Measure low turbidity samples (less than 0.).5ntu) shows its sex and sensitivity.
