Introduction: TFW-3A-type voice digital storage multi-function soil analyzer is based on the TFW-Ⅲ type has been improved, with TFW-TFW-3A type, with the photoelectric colorimetric analysis, electrode potential analysis, conductivity analysis and ground temperature, Water temperature, temperature measurement and other functions. It can not only accurately test the soil nitrogen, phosphorus, potassium, organic matter content, but also on the soil pH, salt and formation temperature measurements. TFW-ⅢA-type instrument set the voice of the number of reports and U disk data storage capabilities, to maximize the convenience of users of the instrument recording and data storage. The instrument can be used for agriculture, forestry, animal husbandry, industry, health care, teaching experiments and other aspects of conventional colorimetric, PH value, conductance, temperature determination, but also can be used for field soil nutrient rapid measurement. With a multi-purpose machine, convenient and intuitive, is the relevant laboratories, agricultural institutes, soil fertilizer station and grain, cotton, vegetables, fruit, flowers and other planting one of the preferred equipment. In order to facilitate field work without AC power, the instrument is equipped with high-quality rechargeable batteries, fully charged, it can provide about 12 hours of stable DC power supply, eliminating the worry of no electricity. In addition the instrument due to the use of high-performance integrated circuits, anti-interference ability, data display is stable and reliable; test process intuitive and convenient. In the photoelectric colorimetric part of the apparatus according to 90214274? 7 national patent set logarithmic output. Technical Parameters: Digital Display Photoelectric color wavelength range: 410nm-750nm Test sensitivity: ± 0.01 Test accuracy: Optical colorimetric analysis of concentration file: Soil available phosphorus: ± 1ppm; Soil available nitrogen: ± 5ppm; Soil available potassium: ± 5ppm; Ground temperature: ± 0.2 ℃ (measuring range: + 2 ℃ - + 50 ℃); PH (pH value): ± 0.02PH Soil salt (conductance): ± 10% (10μs-100μs; 2ms-10ms) ± 0.5% (2μs-10μs; 0.1ms-2ms) ± 1% Use of the environment: Temperature +5 ℃ - +40 ℃ Humidity ≤85% RH AC power: 220V ± 10% DC power supply: 12V / 1.2AH × 2 rechargeable battery Rotary colorimetric tank, you can put six cuvettes at the same time Volume; 335 × 266 × 175 (mm) Weight: 6.5kg Power: 20W Optoelectronic colorimetric analysis direct measurement direct reading, without drawing
a curve.
