Chlorophyll content measuring meter BCHL-B

laboratoryhand-helddigital

Min measuring interval: < 3s Measuring Range: 0.0-99.9 SPAD, -10~99.9°C Accuracy: ±3.0 SPAD; ±0.5°C Operating temperature: -10-50°C Description Chlorophyll Meter is able to measure chlorophyll content of plants and leaf temperature. Chlorophyll content and leaf nitrogen content have a very close relationship.Thus, chlorophyll content can reflect plants demand for nitro. Using the instrument can do go to put nitrogen fertilizer reasonably, improve utilization of nitrogen and protect environment.
