What are the causes of water quality detector errors?
Oct 23,2024
Introduction:
Water quality detection mainly uses a certain method to complete the detection of water quality, but this detection data is usually not expressed in a limit number, coupled with the lack of scientific and technological capabilities, this detection value and its authenticity have a certain gap, this is the "error".
We can look at it from the following points: If the error is divided according to nature and production, it can be divided into three possibilities: systematic, random, and negligent errors.
1. Systematic error, also known as measurable error and constant error, refers to the error between the total value of the detection amount and the true value, which is caused by some constant factors in the working process. For example, the more turbid the water is, the greater the error of the detection. In severe cases, it will cause the inability to detect. In addition, using inappropriate instruments to detect a certain parameter of the total water quality may cause large errors in water quality detection. If under certain conditions, the system error will be repeated. If the data of repeated detections are almost the same, there is no need to continue. It can only mean that the error of the equipment itself is large.
2. Random error, which can also be called accidental error, is caused by the combined effect of various random factors in the detection process. This error will affect the measurement results due to some small fluctuations of many uncontrollable or controlled factors! If it is caused by environmental problems and other factors during the detection process, it can be seen as the superposition of errors caused by a large number of random factors.
3. Negligent error, also called gross error. This type of error obviously distorts the measurement results. This is because mistakes that should not be made are made during the work process, such as poor maintenance, wrong reagents, and wrong samples. Errors may occur. There is no certain rule for negligent errors.
The principle of the GENESITE instrument multi-parameter water quality detector GNST-900S is in line with the recognized method of the environmental protection industry. The equipment uses a solid-state cold light source and an ST32-bit ARM processor, which has more stable optical performance. The equipment is equipped with the independently developed Genesite water quality intelligent detection system, making the detection simpler and more stable.
