Knowledge of purchasing sensing faucets

1. Process of faucet: The appearance is free of scratches, and whether the chrome plating is good or not. It is made of brass. The chrome plating and weight of low priced sensing faucets on the faucet body are poor, and they cannot pass the 24-hour salt spray test, with a weight of about 400 grams. However, good sensing faucet manufacturers can control the weight of the faucet body to over 500 grams, and can pass the 48-hour salt spray test, with a long service life of the faucet.

2. Whether the infrared sensing part is sealed with epoxy resin or moisture-proof treatment, and the connection plug is equipped with waterproof plug. The line is controlled by a low-power microcontroller, which has anti-interference ability to light without misoperation; The sensing distance is adjustable using a remote controller. Manual adjustment can easily damp the circuit board, shorten the sensing distance, and affect normal use; Automatic distance adjustment technology is not mature and can shorten the distance due to color changes. Remote control makes the product more user-friendly.

3. The electromagnetic valve part has good waterproof performance. Due to long-term installation under the basin, the machine will cause poor contact after being damped, making the machine not work; The low life of the solenoid valve should meet the industry standard (over 150000 times).

4. Try to choose qualified manufacturers that produce sensing faucets. As more than 90% of sensing faucets produced by domestic sanitary ware factories are outsourced, they are not satisfactory in terms of quality, after-sales service, and price; In the domestic sensing faucet industry, there is a lack of brand and leading brands. Many customers use sanitary ware and bathroom related brands as reference standards in their selection, mainly recognizing sanitary ware brands, pursuing uniformity in their selection, and often lacking product accessories and personnel services during later maintenance.

5. After-sales service capability: Don't trust too many promises and guarantees. Some manufacturers and businesses have promised 5-year warranty exemption in order to expand sales, and have attracted customers' attention at low prices. The company has not developed for more than two years. When there are real product quality issues or product warranty issues, they charge customers maintenance fees, and have not implemented the three-guarantee policy related to the product. The consumer rights and interests of many users cannot be guaranteed.
