GT300-LTUB Ultra-low Laser Turbidity Analyzer uses laser as the light source. When the laser beam penetrates the defoamed liquid sample flowing into the interior of the instrument, the particles in the sample will scatter the laser beam, and the optical fiber sensor is used to capture the 90° scattered light. The turbidity value can then be analyzed based on the intensity of scattered light.
The turbidity of water is caused by suspended matters such as organic and inorganic substances, plankton and other microorganisms. Turbidity is a kind of expression of the optical properties of water samples, which is proportional to light scattering in the sample. Turbidity measurement is generally divided into surface scattering method and internal scattering method of sample. For internal scattering method, the color absorption and particle scattering will attenuate during the transmission of incident light in the sample. Except for sensitivity to color perception, its measurement range is smaller. However, as the continuous GT300-LTUB Ultra-low Laser Turbidity Analyzer adopts laser as the light source, it has a large measurement range and good linearity.
■ No contact of optical components with the water sample to rule out frequent cleaning of the probe and greatly reduce maintenance costs.
■ It uses LED light source with the advantages of low power consumption, stable light intensity, long light source service life of 100,000 hours, no replacement of light source regularly, and low maintenance work to greatly reduce maintenance costs.
■ It uses laser modulation and phase detection technology to improve system sensitivity and stability. The laser light source has good monochromaticity to eliminate the influence of stray light on measurement, and ensure measurement accuracy.
■ A special defoamer device will eliminate air bubbles in the sample and reduce the effect of air bubbles on measurement.
■ The digital sensor supports Modbus protocol, plug-and-play, strong anti-interference ability, and long cable length of up to several hundred meters.
■ Optional DC power supply for solar power and other operating conditions are available.
■ Historical data is displayed graphically, and time can be switched freely to display in minute, hour and day.
■ 8G memory card to save historical data.
