HM-YA chlorophyll meter Introduction: The HM-YA chlorophyll meter can instantly measure the relative chlorophyll content (unit SPAD) or "greenness" of plants, thereby understanding the actual nitro demand of plants and helping you understand the degree of soil nitro deficiency or whether nitrogen fertilizer is applied excessively. You can use this instrument to increase the utilization rate of nitrogen fertilizer and protect the environment (preventing excessive application of nitrogen fertilizer from polluting the environment, especially water sources). Technical parameters: 1. Measurement range: 0.0-99.9 SPAD 2. Measurement area: 2mm * 2mm 3. Measurement accuracy: Within ± 1.0 SPAD units (at room temperature, SPAD values range from 0 to 50) 4. Repeatability: Within ± 0.3 SPAD units (SPAD values range from 0 to 50) 5. Measurement time interval: less than 3 seconds 6. Data storage capacity: 2GB 7. Power supply: 4.2V rechargeable lithium battery 8. Battery capacity: 800mah 9. Weight: 250g 10. External dimensions: 140 × eighty-five × 45mm (length × wide × High 11. Working and storage environment: 0 ℃ -50 ℃; 85% relative humidity
