Product Description

Plant chloroplasts can instantly measure the relative content of chlorophyll(unit SPAD) or green, leaf surface temperature of plants, so that you can understand the true demand of plants for Nitrogen. You can use this instrument to increase the use of nitrogen fertilizer and protect the environment(prevent excessive application of nitrogen fertilizer to pollute the environment, especially water sources).
