YLS-A chlorophyll analyzer Introduction: The chlorophyll meter can measure the relative chlorophyll content or "green degree" of the plant instantly. The chlorophyll content in the leaves of the plant indicates the condition of the plant itself, and the leaves of the well-growing plant contain more chlorophyll. The content of chlorophyll is closely related to the content of nitrogen in leaves. Therefore, the measured value of chlorophyll can also explain the real demand for nitro-nitro in plants. This instrument is helpful for the rational application of nitrogen fertilizer and the improvement of nitrogen utilization rate. And can protect the environment (prevent excessive application of nitrogen fertilizer and make the environment, especially water pollution. Technical parameters: Features: Measuring time fast Direct display of chlorophyll value by LCD The instrument is small and portable and can be carried to the field Measuring samples: various plant leaves Measured area: Ф10mm Measurement mode: 2 wavelength optical concentration difference mode Inductor: Silicon semiconductor photodiode Display mode: measuring value: 3 digit liquid crystal display Measure number of times: 2 digit liquid crystal display Minimum interval of measurement: less than 2 seconds Measurement range: 0. 0 ~ 99. 9 Spad Accuracy: ±1.0 SPAR (SPAR value between 0 and 50 at room temperature) Repeatability: ±0.3 SPAD-less unit SPAR value between 0 and 50) Reproducibility: ±0. 5 SPAD-less than 0 ~ 50) Operating temperature: 0～50℃ Storage temperature: 20～55℃ Memory capacity and keystroke function: 30 data, calculate and display the average value automatically Power switch: on is on and off is off; AVG (mean value) key: calculate the average of the data in memory; DEL (clear all data) key: erase all data in instrument memory; Display key: display the data stored in the memory of the instrument; Meas key: press MEAS key to measure. Electric Source: 2 Section 5 Battery Battery life: two batteries per set can last more than 20000 operations Volume (length × width × high): 155mm × 70mm × 42mm Weight: 320g (excl. batteries).
