The performance we refer to actually means the extent to which a water quality monitor can achieve its intended functions. Performance characteristics are some parameters and quantitative expressions standardized to determine the performance of the instrument.
Then, as consumers, it is very important to be familiar with the performance characteristics of the monitoring instrument! How should I put it? For instance, stability is a kind of performance of equipment, and the main parameters for measuring stability are zero drift and range drift. Simply put, stability here is usually expressed by zero drift and range drift. The performance characteristics we refer to are quantitatively expressed through a certain quantity value, range, etc., which can be called “performance indicators”. There are many types of water quality monitors mentioned in this article, and their functions will of course vary. However, the performance characteristics have a broad meaning and can mainly be divided into two categories:
1.The performance characteristics are closely related to the working range and conditions of the monitor.
The working range mainly refers to the object to be measured, the range and the measurement range, etc. The working range of different monitoring instruments is also different. In addition, the working conditions mainly refer to the adaptability to environmental conditions and the requirements for sample conditions, etc. If the user directly installs the monitor at the industrial site to analyze the materials in the process flow, the instrument has very strict requirements for adaptability to environmental conditions and sample conditions. Of course, when compared with these analyzers in the laboratory, there are still significant differences among these online monitoring instruments (such as: online coliform bacteria analyzer, online total residual chlorine analyzer, online water quality bacterial count monitor, etc.).
2.The performance characteristics and the analysis signals of the instrument are directly related to its response value.
It can be said that the numerical values and dimensions of such performance characteristics vary for different instruments, but they share a common feature: the definitions are the same. They are performance characteristics shared by different types of monitors and are also important data for comparing instruments of the same category. At the same time, they are also important parameters for evaluating their basic performance. Such performance characteristics mainly include accuracy, repeatability, stability, linear range, response time and other conditions.
