Brief introduction: Chlorophyll meter can real-time measuring plant chlorophyll relative content or the "green degree" of plant leaf chlorophyll content is an indicator of the status of the plant itself, grew well in the plant's leaves contain more chlorophyll, chlorophyll content and nitrogen content in the leaves have a close relationship, therefore the chlorophyll measurements can also explain the real demand of nitrocellulose plant, through this kind of instrument is beneficial to reasonable applying nitrogen fertilizer, improve the utilization rate of nitrogen, and can protect the environment (prevents excessive nitrogen fertilizer and make the environment especially the pollution of water source) Technical parameters: Measuring samples: all kinds of plant leaves Measurement area: Ф 10 mm Measurement method: two wavelength optical concentration difference method Sensors: silicon semiconductor photoelectric diode Display mode: measurements: 3 digit LCD display Numbers: 2 digit LCD display Measure the minimum interval: less than 2 seconds Measuring range: 0.0 to 99.9 SPAD Accuracy: + / - 1.0 SPAD (at room temperature, SPAD value ranges from 0 to 50) Repeatability: SPAD unit within 0.3 mm (SPAD value ranges from 0 to 50) Repeatability: SPAD unit within 0.5 mm (SPAD value ranges from 0 to 50) Electricity source, section 2 5 AA alkaline manganese battery or carbon zinc batteries Battery life: each group of two batteries can last more than 20000 operations Volume (length x width x height) : 155 mm * 70 mm * 42 mm Weight: 320 g (not including battery)
