The environment is very bad, with all kinds of garbage floating on it, including oil and water. And they just jumped right in without any measures. My suggestion to them is to make a box outside and wrap it up like stockings. Even with this approach, the shelf life of the product is worrisome.
The environment is also bad, and it was already covered with floc within two days of installation. The dissolved oxygen is basically good, but there will be a value of 0 around 3 a.m.. When I opened it and found that there is no problem, I can only speculate that it is caused by the factory secretly discharging it in the middle of the night. The same situation is true for ammonia
nitrogen.
The water quality at this point is good and all values are normal. Since the water flow is relatively large, it is recommended that the other party make a barrel-shaped hole with a small hole on the side, and then put the instrument in, which will be more secure.
The left side shows the installation method of underground manholes. In this environment, the flow rate of water, the size of impurities in the water, etc. must be considered. On the right, the water environment of an ordinary river is relatively good. This is a small system that can remotely view the local water environment in real time. Using solar energy is environmentally friendly and convenient.
For this environment, it is a challenge for the sensor because of the turbulent water flow and full of bubbles. You must be prepared for use in this environment. Ask for relevant knowledge in
Advance.
This kind of cabinet is built directly beside the river to monitor water quality in real time. It looks very beautiful and simple, but power supply and ambient temperature must be considered when selecting a site.
