Recently, Mr. Tian, ​​who lives in the A district of R&F City, the provincial capital, asked the reporter: "The cabinets that have just been installed in the home have fallen out of the drawer in three months, and the door has a tendency to slip. If it is a hardware problem, you can Is it necessary to repair and replace the cabinet?"
The reporter learned that cabinet hardware accessories play an important role in connection, stretching and storage. The frequently used drawers, the load-bearing capacity of the slide rails and the pulling technology determine the service life of the whole cabinet. In the whole cabinet, there are always some corners and corners that are not fully utilized. Some hardware accessories can help. However, if the hardware is of poor quality or the installation is not strong, it may cause terrible safety problems due to load bearing.
The engineering supervision of Huayou Decoration Company told the reporter: "If it is just a simple screw loose, as long as it can be found in time, it is enough to buy the matching screws. But if the quality of the product itself is not up to standard, or it is aging or even rusting, It is recommended to replace it as well."
Buying the cabinet itself is already a very tedious task, and the billing problem of hardware is even more troublesome. When ordering cabinets, the cabinet manufacturer price already includes a set of "standard" hardware accessories, including hinges, drawer slides, handles and handles, support, etc. If these accessories have problems, can you request replacement repair? In fact, Hardware is generally not produced by the cabinet manufacturer, so there will be its own manufacturer and warranty period, the purchase and the sales staff need to be confirmed separately, and ask for the warranty.

The concentration of chlorophyll in the water body reflects the content of phytoplankton. Monitoring the content of chlorophyll in water can determine the degree of eutrophication of the water body, and provide early warning of water pollution, algae blooms, and red tides. The chlorophyll sensor adopts the measurement principle of fluorescence method: the substance to be measured is irradiated with excitation light of a certain wavelength to excite it to a high-energy state, and when it returns to the ground state from the high-energy state, it will emit fluorescence greater than the excitation wavelength. The excited fluorescence intensity is the same as that of the substance to be measured Concentration dependent. Digital chlorophyll sensor is an online electrode with RS485 communication interface and standard Modbus communication protocol. Based on fluorescence optical method technology, the chlorophyll sensor has strong anti-interference, high sensitivity, no need for pretreatment, fast measurement, and can measure chlorophyll a of water quality. The chlorophyll sensor is used for plants, algae growth, water eutrophication; early warning of algae outbreaks; the best choice for studying water ecosystems.
