In household appliances, the use rate of refrigerators is relatively frequent, but the service life of durable appliances is generally 10 to 12 years. In daily life, if used improperly, it may cause the refrigerator to “prematurely fail†and end its own service life in advance. Of course, in the actual operation process, as long as we pay attention to some of the use of details can also play a corresponding maintenance role. For example, frequent switching of the refrigerator door may seem like a trivial matter, but it will increase the cooling loss in the refrigerator cabinet to varying degrees, affecting the cooling effect, and will increase the energy consumption in vain. Pulling the drawer of the refrigerator vigorously may also cause corresponding damage to the refrigerator, which may affect its service life more or less. If it is not the cause, it is best not to disable the refrigerator. If it is because of special factors such as long-term outing, it is best to break the power supply, wipe the refrigerator room with a clean rag, and leave a small gap in the door after it is fully dry, so that the air inside and outside the box can circulate, avoiding the mold residue in the box. change. In the cleaning and maintenance of the refrigerator, it is best not to use detergent, decontamination powder, talcum powder and alkaline detergent, and do not use a brush to force the brush, etc., so as not to damage the outer coating of the box and the plastic parts inside the box, or damage Refrigerator liner and tubing. It is advisable to gently scrub with a soft cloth dampened with water, and then thoroughly wipe off the remaining detergent with water. After cleaning, wait for about 3 minutes to re-energize and check if the temperature is set correctly. Place it in a dry and ventilated place, at least 20 cm from the wall, and try not to get close to the heat source and avoid sunlight.

Water quality chlorophyll content refers to the concentration of chlorophyll in water. Chlorophyll is a green biopigment that widely exists in plants, algae and some protists and is a key molecule in photosynthesis. The chlorophyll content in the water body can reflect the biomass in the water body and the health of the ecosystem. High chlorophyll content usually indicates eutrophication of the water body and may lead to eutrophication phenomena such as cyanobacterial blooms and hypoxia. The online chlorophyll analyzer adopts the advanced principle of fluorescence method, which can reduce the influence of stray light and has excellent repeatability and stability. RS485 digital interface, supports Modbus protocol, the Chlorophyll Sensor adopts an environmentally friendly design, with an automatic cleaning brush, and the cleaning time and interval can be set on the Chlorophyll Controller. Chlorophyll analyzers are of great significance to the protection of water environments and ecosystems. Daruifuno online chlorophyll meter is used for measuring the chlorophyll a in water, it is widely use for surface water monitoring.
