Product Introduction:

JR-TFW3 typeSoil nutrient analyzerYes, it isJR-On the basis of TFW2 type, it has been simplifiedJR-Like the TFW2 model, it has multiple functions such as photoelectric colorimetric analysis, electrode potential analysis, conductivity analysis, and measurement of ground temperature, water temperature, and air temperature. It can not only accurately test the content of nitrogen, phosphorus, potassium, and organic matter in soil, but also measure the acidity, salinity, and formation temperature of soil. Retained in photoelectric colorimetric analysisJR-The concentration analysis part of TFW2 type; Ground temperature is measured using a single point method. This instrument can be used for various conventional colorimetric, pH, conductivity, temperature measurements in agriculture, forestry, animal husbandry, industry, medical and health, teaching experiments, and can also be used for rapid measurement of soil nutrients in the field. It has multiple functions and is convenient and intuitive, making it one of the equipment for relevant laboratories, agricultural science institutes, soil and fertilizer stations, as well as grain, cotton, vegetable, fruit, flower and other planting households. For the convenience of field operations without AC power, this instrument is equipped with high-quality rechargeable batteries. After being fully charged, it can provide stable DC power for about 12 hours, eliminating the worry of no electricity. In addition, due to the use of high-performance integrated circuits, this instrument has strong anti-interference ability and stable and reliable data display; The testing process is intuitive and convenient.
