A profilometer is a precision equipment used to measure the shape of various mechanical parts' lines and cross-sectional contours. The instrument workbench adopts high-precision horizontal air floating track and rolling vertical track, with high movement accuracy, good stability, and long service life; High measurement efficiency, simple operation, suitable for use in workshop inspection stations or measurement rooms. The instrument workbench adopts high-precision horizontal air floating track and rolling vertical track, with high movement accuracy, good stability, and long service life; High measurement efficiency, convenient card installation, simple operation, suitable for use in workshop inspection stations or measurement rooms. This instrument can further develop software according to the needs of users, meet their measurement shape requirements more widely, and is equipped with various equipment components for users to choose and use according to their own requirements. A Profilometer is a precision equipment used to measure the shape of various mechanical parts' lines and cross-sectional contours. In the bearing industry, it is possible to measure the contour shapes of various rolling elements and raceways, such as protrusion, contact angle, surface curvature radius, and reference part angle. In the mechanical industry, it is possible to measure the straightness, line profile, parallelism, inclination, and angle of various parts. Especially suitable for measuring the appearance of pistons in automobiles, tractors, and motorcycles. The production instruments of this research run enterprise are controlled by microcomputers, which automatically achieve measurement cycles, eliminate installation errors, directly display the shape and parameters of the measured parts, and can print graphics and data for product quality testing and process analysis.

Fresh flowers and soybean pods preserved at room temperature
Both flowers and cardamom are popular food items that people enjoy, but due to seasonal limitations, they aren't available all year round. Now, we introduce a simple and cost-effective preservation method that only costs a few cents per kilogram and can boost income by several times.
**For Peanuts:**
After harvesting, the worst-quality peanuts are selected, washed with clean water, and then treated with a special peanut storage agent (available at chemical stores). They are heated for 6 to 8 minutes, cooled down with cold water to room temperature, and then dried. Once dried, they can be stored at room temperature. The cost of storing fresh peanuts is just 2 cents per kilogram. After storage, these peanuts can be eaten directly or sold when fresh ones are not available. They remain crispy, fragrant, and delicious, and can also be cooked in various ways—such as spicy, salty, or aromatic flavors—which makes them very popular among consumers. This method increases economic returns by more than three times.
**For Soybean Pods:**
Soybeans harvested during the milky stage are picked, washed, and soaked in a 0.2% color-protecting agent for 30 minutes. Then, they are placed in an open-water broth with a special freshness-preserving agent for green soybeans for about 3 minutes. After being cooled with cold water to room temperature, they are soaked again in the 0.2% color protector solution for another 30 minutes. Finally, they are dried and stored at room temperature. When fresh soybean pods are not available, they can be sold after soaking in water, costing only 2 cents per kilogram. This process increases profit by 3 to 5 times, making it a highly profitable option for farmers and sellers alike.
This preservation technique not only extends the shelf life of these products but also opens up new market opportunities throughout the year, ensuring consistent demand and higher profits. It's an easy-to-implement solution that brings real value to both producers and consumers.
