Spring cultivation fertilizer anti-counterfeiting

Spring is the peak season for sales and use of chemical fertilizers. In order to prevent the purchase of counterfeit and shoddy products, several simple identification methods are introduced based on the characteristics of fake deteriorating fertilizers on the market. 1, see the packaging. Where qualified chemical fertilizers are produced by regular manufacturers, their packaging bags are usually marked with the product name, nutrient content, net weight, and origin etc.; false degraded fertilizers have rough packaging and high breakage rates; signs are incomplete or illegible, and sometimes Do not use Pinyin for Chinese characters to impersonate imported fertilizer. 2, see the price. As the saying goes: "Cheap without good goods." The price of fake fertilizers is generally lower than the price of similar high-quality fertilizers on the market. 3, see the variety. Pseudo-deteriorating fertilizers are generally based on compound fertilizers (such as diammonium phosphate, etc.), urea, superphosphate, liquid fertilizers, and foliar fertilizers. When buying these chemical fertilizers, special care must be taken; ammonium bicarbonate and other fertilizers are on the market. Few fakes appear. 4, look at the appearance. Different chemical fertilizers often have different appearance characteristics, such as ammonium bicarbonate is white, with a strong ammonia odor; urea, ammonium sulfate, ammonium nitrate, ammonium chloride are all white granular crystals; calcium carbonate is gray powder, there are Sour taste; three-material superphosphate is a greenish gray, large and uniform particles, no odor; calcium magnesium phosphate fertilizer is a white powder, no odor; potassium sulfate is a white powder crystal, no odor; Diammonium phosphate is yellow gray or iron Gray particles, uneven particle size, volatile in wet environments, ammonia smell. In addition, ammonium sulfate such as ammonium sulfate, ammonium nitrate, and ammonium chloride, and ammonium phosphate such as diammonium phosphate compound fertilizers are obviously placed on palms with a small amount of grass ash (or alkali or lime). Ammonia smell. If the fertiliser encountered is obviously inconsistent with its characteristics, it can be concluded that it is a fake deteriorating fertilizer.

Small 2D LiDAR Sensor

IT02S, is JRT new product in the early 2019, which is a single-point LiDAR sensor, also called tof distance sensor. With a micro size of 46x17x7mm, customers can widely use in many Laser Measurement Solutions. The lidar distance sensor can measure 12m short-range with high frequency up to 100hz. It's great for Unmanned Aerial Systems. If you need us send you data sheet and spec for this products, offering sample as well, pls tell us, thank you.
