We know that in the process of water quality monitoring, regardless of what parameters are being measured, their accuracy is equally important. Inaccurate monitoring results can cause certain negative impacts. Maybe someone will ask, “Which water quality monitoring equipment is better? What methods are better for monitoring?” With a phrase from online language, “Do children have many question marks?” As a professional manufacturer of water quality monitoring instruments, Hangzhou Modi, how is it exactly?
The choice of instruments and methods for water quality monitoring depends on different standards and parameters. Hangzhou Mudui’s water quality monitoring instruments are mainly divided into two types: dedicated type and multi-parameter monitoring type.
1.For multiple parameters of water quality, they are monitored through one device, called multi-parameter online analyzer. There are two-in-one, three-in-one, and four-in-one types. The parameters here are: COD, ammonia nitrogen, total phosphorus, and total nitrogen.
2.If it is a dedicated type? It mainly monitors and analyzes one parameter. For example, monitoring active oxygen in water, it directly uses ROS900 Active Oxygen Online Analyzer and other single-parameter monitoring devices.
However, regardless of whether it is a multi-parameter type or a dedicated type, Hangzhou Mudui’s water quality monitoring instruments are all fully automatic types. They have advantages such as convenient analysis operation. But in terms of accuracy, our staff usually recommend users to purchase dedicated types because, after all, there is a professional field for each type. Specialized and multiple types are more reliable. Of course, some users, due to various reasons, insist on needing multiple parameters. So, is the monitoring result reliable? This is actually hard to say. The equipment is used to detect data of corresponding water quality indicators. The qualification of some indicators does not mean that all indicators are up to standard. So we need to understand one thing: if the water quality monitoring result exceeds the standard, it indicates that there is definitely a problem with the water quality. But the qualification of a certain or a certain indicator does not mean that the water quality is safe.
For Hangzhou Modi’s water quality online monitoring instruments, reagents are needed. Different monitoring objects use different methods. So many things are not absolute. It still needs to be decided based on one’s own situation.
