The laboratory turbidity analyzer is a very precise turbidity measuring instrument. Based on the 880nm infrared light source passing through the optical lens and penetrating the sample liquid, according to the principle of scattered light in the direction of 90°, this high-range online laboratory turbidity analysis The instrument can be used to measure the turbidity of raw water or pure water on filter devices in different places, such as drinking water, various production and industrial water, and any place where qualified water is required. The product has a compact structure, built-in backlit LCD screen, data memory, relay control output (3 channels). The turbidity controller outputs a 4~20mA isolated signal to transmit reliable data for any place that needs to monitor and control turbidity. Turbidity is measured with an instrument called a laboratory turbidity analyzer. Laboratory turbidity analyzers send light through a section of sample and measure how much light is scattered by particles in the water at a 90° angle to the incident light. This scattered light measurement method is called scattering method. Any true turbidity must be measured this way. The laboratory turbidity analyzer is suitable for both field and laboratory measurements, as well as continuous monitoring throughout the day. Laboratory turbidity analyzers can be set to sound an alarm when measured turbidity values exceed safety standards. Turbidity can also be estimated by using a colorimeter or spectrophotometer to measure the degree of attenuation of transmitted light intensity caused by the obstruction of particulate matter in the sample. However, regulatory agencies do not recognize the validity of this method, nor does it meet the Public Health Association's definition of turbidity. Common faults and solutions of the laboratory turbidity analyzer: 1. The power light is not on. The power light is not on, which may be due to poor contact with the power supply. This problem can be solved by reinstalling the power supply after checking the plug and socket. Another reason why the power light of the laboratory turbidity analyzer is not on is that the fuse inside the laboratory turbidity analyzer is blown, which requires the user to replace a new fuse for the laboratory turbidity analyzer. 2. Low reproducibility In addition to the cause of the failure of the sample cup itself, there are two other possibilities. One is the change of the placement position of the sample cup used by the laboratory turbidity analyzer, and the other is the sample cup. The difference in the amount of liquid in the cup is too large. When the laboratory turbidity analyzer is measuring, the user can avoid this problem by accurately placing the sample cup and maintaining the liquid level in the sample cup. 3. Unstable readings Unstable readings are not necessarily caused by the laboratory turbidity analyzer itself. Improper operation can also lead to unstable readings of the laboratory turbidity analyzer. When there are many bubbles in the liquid measured by the laboratory turbidity analyzer, the measured value of the laboratory turbidity analyzer will be affected. Therefore, the measurement of the laboratory turbidity analyzer must wait for the bubbles in the aqueous solution sample to dissipate. to proceed.
