A measuring instrument for quantitatively evaluating the cylindricity of a cylinder by measuring the actual contour of the cylinder using the precise rotation centerline as the reference standard and the precise linear motion guide rail as the reference standard. It can be used to measure cylindrical shape errors (roundness, cylindricity, straightness, and flatness), position errors (coaxiality and verticality), etc. The cylindrical Roundness Tester is mainly used to measure the roundness, cylindricity, straightness, concentricity, coaxiality, flatness, parallelism, perpendicularity, surface waviness, discontinuous surface, etc. of various regular and irregular circular workpieces. It can also perform spectrum analysis, wave height analysis, eccentricity, shaft bending analysis, and runout analysis on workpieces. This device has excellent cost-effectiveness, full measurement capability, and is easy to learn and use.

Fresh flowers and soybean pods preserved at room temperature
Both flowers and cardamom are popular foods that people enjoy eating, but due to seasonal limitations, they can't be consumed all year round. Now, we introduce a cost-effective preservation method that only costs a few cents per kilogram and can significantly boost income—up to several times higher.
**For Peanuts:**
After harvesting, the worst-quality peanuts are selected, rinsed with fresh 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, costing just 2 cents per kilogram. These preserved peanuts can be eaten directly or used when fresh ones are unavailable. The texture is crispy, fragrant, and delicious on its own. When cooked, they retain most of the flavor of fresh peanuts and can be boiled into various tasty flavors like savory, spicy, or aromatic, which are highly appealing to consumers. This process can increase 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 into an open-water broth containing a special freshness-preserving agent for green soybeans and cooked for about 3 minutes. Afterward, they are cooled with cold water to room temperature and re-soaked in the 0.2% color protector solution for another 30 minutes. Once dried, they can be stored at room temperature. When fresh soybean pods are not available, they can be sold after soaking in water. At just 2 cents per kilogram, this method can increase profits by 3 to 5 times.
This innovative preservation technique not only extends the shelf life of these agricultural products but also opens up new market opportunities, allowing farmers and sellers to maximize their earnings throughout the year.
