A digital refractometer is an instrument used to measure the refractive index of a substance. It works by shining a beam of light through a sample and measuring the angle at which the light is bent. The refractive index is then calculated based on this angle and the properties of the material being measured. Digital refractometers are commonly used in the food and beverage industry to measure the sugar content of liquids such as fruit juices and wine. They are also used in the automotive and chemical industries to measure the concentration of various fluids. Digital refractometers offer the advantage of being more accurate and easier to read than traditional analog refractometers.

Lock handle products open hardware market
In the world of interior design, people often find themselves drawn to the elegant look of a door or a closet. However, when they take a closer look, they might be disappointed by the hardware—handles, hinges, or locks—that seem out of place with the overall aesthetic. But times are changing. More and more hardware is now designed not just for function, but as a piece of art. It's no longer the door that catches your eye, but the beautifully crafted lock on it.
With the booming real estate market and the rapid pace of urban development, the demand for decorative hardware has significantly increased. Though small in size, these products have evolved to offer more refined and stylish options. Gone are the days when locks were simply functional. Now, they come in a wide range of styles, some even resembling flowers or animals, yet still serving their primary purpose: security.
In today’s market, popular door locks include spherical designs, round cover handles, embedded long covers, and handle-type locks. For internal doors, channel locks and auxiliary locks (with strong anti-theft functions) are particularly favored. According to market research, most locks are made from brass, stainless steel, or bronze, with surface finishes combining two colors. Prices vary, with door locks typically starting at over 100 yuan, while some can go up to 800 yuan or more. Interior door locks, on the other hand, are more affordable, with high-quality options available for around 80 yuan.
Handles, too, have become a major design element. While they serve a practical purpose, their appearance often makes them stand out. No longer limited to simple stainless steel, modern handles come in various colors such as black, bronze, light chrome, pearl nickel, and even transparent paint. Some are crystal clear, others dark and mysterious—each reflecting a different style. These subtle touches add personality to any space, making them more than just functional pieces.
In terms of style, straight-lined minimalist handles and rugged European-style aluminum ones are currently trending. Sizes range from 32mm to 384mm, offering flexibility for different applications. Some metal handles even feature animal-shaped designs. During an interview, a customer was delighted to see an elephant-shaped handle and expressed interest in creating a new dressing cabinet at home, all for just 20 yuan.
Imported brands from Germany and Italy dominate the market, but creative and unique pull handles are also becoming popular. Some of these are surprisingly affordable, costing around 15 yuan—cheaper than many branded alternatives. Our own brand, "Boli Ya," offers high-quality, innovative designs that combine functionality with aesthetics. We invite you to explore our collection and discover the beauty of modern hardware.
