Soil comprehensive analyzer • Water quality comprehensive analyzer (printable, computer compatible)

The instrument is equipped with USB interface and printer interface, which can be connected to a computer through the USB interface and achieve storage, printing and other functions through the computer. The printer interface can be connected to the printer for direct printing. This instrument can not only perform various analyses on soil, but also on water quality. In soil analysis, it can not only accurately test the content of nitrogen, phosphorus, potassium, and organic matter in soil, but also measure the acidity, salinity (conductivity), other trace elements, and formation temperature of soil. In addition, it can also detect fertilizers. In water quality analysis, in addition to measuring various functions related to soil (such as ammonium nitrogen, nitrate nitrogen, pH value, conductivity, temperature, etc.), dissolved oxygen and turbidity in water can also be determined. For the convenience of field operations without AC power, the instrument is equipped with high-quality rechargeable batteries, which can provide stable DC power for about 12 hours after being fully charged. Eliminating the worry of no electricity.

Soil comprehensive analyzer • Water quality comprehensive analyzer (printable, computer compatible)In the photoelectric colorimetric analysis section, the instrument is equipped with logarithmic output according to the national standard 90214274 • 7. In the formation of logarithmic curves, the machine is specially designed with a direct adjustment knob, which can avoid the trouble of drawing curve graphs when using a general spectrophotometer for photoelectric colorimetric analysis; It is possible to directly measure and read the concentration values of various substances and the turbidity values of water quality from this machine. This instrument can be used for various conventional colorimetric, pH, conductivity, temperature, dissolved oxygen, and turbidity measurements in agriculture, forestry, animal husbandry, industry, medical and health, teaching experiments, and other fields. It can also be used for rapid measurement of soil and lake water quality in the field; It has multiple uses and is convenient and intuitive. It is one of the equipment used by relevant laboratories, agricultural science institutes, soil and fertilizer stations, as well as farmers engaged in grain, cotton, vegetable, fruit, flower, and fishery breeding.
