Troubleshooting method of turbidity online detector

In most people's perception, clear water is healthy, and turbid water must be problematic. In fact, it is not the case. This mainly depends on the content of suspended solids in the water. The turbidity online detector can measure the turbidity of water, and the accuracy can reach about 0.01 degrees. It can accurately monitor the changes of suspended objects in the water and analyze the quality of water. During the long-term use, due to various reasons, some faults or reading errors may occur, so the operator must master certain simple fault maintenance methods to ensure the smooth progress of production work. 1. The power light is not on. The power light is not on. It may be due to poor contact with the power supply. At this time, check the plug and socket and reinstall the power supply to solve the problem. If it is due to a blown internal fuse, this will require replacing the fuse. 2. The measurement repeatability is low. Generally, the online turbidity detector can perform repetitive experiments. If the measurement result has low repeatability, it may be that the position of the sample cup used is changed, or the amount of liquid in the sample cup is different. is too big. During the specific operation of the turbidity online detector, the user can avoid this problem by accurately placing the sample cup and maintaining the liquid level in the sample cup. 3. The reading is unstable. If the instrument itself fails or the worker does not operate properly, the reading of the instrument will be unstable. Pay attention to the absence of air bubbles in the aqueous solution sample during measurement. In addition, when the test sample is poured into the sample cup, there is a hanging cup, so that the scattering of light is disturbed, and the result is unstable. 4. Large measurement error The large error of the online turbidity detector may be due to a large error in the previously calibrated curve, which requires the user to recalibrate and calibrate. In addition, if the temperature of the solution to be measured is high, the mist on the cup will also cause errors in the measurement results.
