Product Description: The results of automatic measurement of photoelectric balance are used, and the results of automatic measurement are displayed by dot matrix liquid crystals. It retains both DRK8060, DRK8062 stable and reliable, high sensitivity, no one is the error, and the convenient reading is convenient, and the measurement of the measuring mode of rotation, solution concentration and sugar is greatly convenient. Measurement mode: rotation, ratio of rotation, concentration, sugar Light source: sodium light + color filter, wavelength 589.44 nm Measuring range: ± 45 ° (in degreas) Minimum reading: 0.001 ° (rotation) 0.01 ° Z (sugar) Accuracy: ± (0.01+ measured value × 0.05%) ° (rotation) Repeatability (standard deviation δ): ≤0.003 ° Display mode: dot matrix liquid crystal display Test tube: 200mm, 100mm Minimum transmittance of measurable sample: l0% Output communication interface: RS232 Power supply: 220V ± 22V, 50Hz ± 1 Hz Instrument size: 600mm × 320mm × 220mm Instrument quality: 28kg Instrument level: 0.05
