Five strokes teach you to buy furniture:
Smell the taste: Most of the wooden furniture sold on the market, except for all solid wood furniture, has wood-based panel parts. Therefore, you should especially smell the smell when you purchase. If you make people cry and sneeze, it means that the formaldehyde emission of furniture is relatively high and should not be purchased.
Look at the report: Consumers can ask the dealer for a quality inspection report to see if the amount of formaldehyde released from the furniture is within the limits allowed by the standard. The national standard "Limits of Hazardous Substances in Wood Furniture for Interior Decoration Materials" stipulates that the amount of formaldehyde released in wooden furniture shall not exceed 1.5 mg per liter.
Ask the price: Most of the wood furniture with excessive formaldehyde is cheap man-made boards, so the price of the whole set of wooden furniture is often “ultra-lowâ€.
Signing a contract: When purchasing a piece of furniture, the customer should sign a "furniture sale contract" and write the environmental protection clause into the contract.
Invoicing: Nowadays, a large number of consumers are tempted by dealers' low prices, taking white bars, receipts, etc., and when they go out to complain about quality problems, such informal invoices are often difficult to be effective. Evidence, so to buy furniture, the dealer must issue a formal invoice.
Pressure sensor usually consists of a pressure sensor and a signal processing unit for measuring the pressure of liquids and gases.
According to different test pressure types, pressure sensors can be divided into gauge pressure sensors, differential pressure sensors and absolute pressure sensors. According to the working principle, it can be divided into Ceramic Pressure Sensor, diffusion silicon pressure sensor, piezoresistive pressure sensor, sapphire pressure sensor and so on.
