Soil tester universal soil test instrument SL-2A

Simple and practical, SL-2A soil nutrient tester, soil fertilizer tester, soil tester, soil testing and fertilizer instrument, SHUNLONG soil testing, soil composition analyzer, soil nutrient speed tester, soil tester, soil speed tester, soil tester, test instrument land fertilization technology has an important role in agricultural production: 1, to promote crop nutrient absorption, increase crop yields. 2, fertilizer for fertilizer based on soil conditions and crop fertilizer determined characteristics, can maintain a balanced fertilizer for the soil, but also can improve fertilizer efficiency, reduce fertilizer use. 3, to coordinate crop vegetative growth to reproductive growth and balance, to promote the formation of agricultural products, enhance disease resistance, resilience and reduce the use of pesticides, so as to enhance and improve the quality of agricultural products. 4, according to the characteristics of different crops need fertilizer, targeted fertilization, better play fertilizer use efficiency. 5, to minimize the loss of fertilizer ingredients, reduce the vicious cycle, reduce the chance of environmental pollution for personal cultivation (greenhouses, fruits and vegetables, field crops, etc.), gardens, flowers, agricultural and forestry colleges and other units. First, it can be detected: 1, soil nitrogen, phosphorus, potassium, organic matter and humic acid content. 2, plant nitrogen, phosphorus, potassium, organic matter. 3, fertilizer nitrogen, phosphorus, potassium, organic matter and humic acid content. Second, characteristics: 1, the use of micro-computer chip design, simple operation. 2, high precision, stable data. 3, power storage, be prepared. 4, directly into the test, automatic adjustment. 6, while the test, the sample data memory 12, to reduce the test cost. 5, Table fertilization, at a glance. 7, the power can be used without preheating, energy saving. 8, can be vehicle-mounted, easy to use. 9, exquisite aluminum casing, shock resistance, service life more than a decade. Third, performance indicators wavelength range: * Red 650nm (bandwidth, type) * blue 440nm (bandwidth, type) test error: ± 2 RU * * copper sulfate potassium dichromate ± 6 BU shock resistance: Qualified as power supply: 1. AC: 220V (indoor lighting, electricity may be) 2, DC: 9V-12V 3, connected to the car cigarette lighter to use Service: One year limited warranty Lifetime warranty: Beijing Shun Science and Technology Development Co., Ltd.
