A lightweight handheld meter for measuring the chlorophyll content of leaves without causing damage to plants. (Konica Minolta) Introduction. The SPAD meter determines the relative amount of chlorophyll present by measuring the absorbance of the leaf in two wavelength regions(650 and 940) Although the dual-wavelength meter was slightly more accurate than the single-wave-length meter (higher r2), the light-scattering properties of leaf cells and the nonhom-ogeneous distribution of chlorophyll in leaves appear to limit the ability of all meters to estimate in vivo chlorophyll concentration. Leaf chlorophyll content is often well cor Measuring chlorophyll in water enables you to gain an understanding of the natural levels of chlorophyll present in the water, and to recognise if there is a change, which could be an indication that a pollutant has entered the water.

However, chlorophyll meters, for example the SPAD-502 (Spectrum Technologies, Plainfield, Illinois, USA), provide a simple, quick and nondestructive method for estimating leaf chlorophyll content. Abstract. We conducted two experiments to determine the usefulness of a chlorophyll content meter (CCM) for the measurement of foliar chlorophyll concentration in sugar maple (Acer saccharum Marsh.) in the fall color period.In Experiment 1, four sugar maple trees were visually assigned to each of four fall foliage color categories in October 1998 The chlorophyll meter (for example, the Minolta SPAD 502) is a small, handheld device that instantly measures the greenness of plant leaves. The leaf greenness is related to the chlorophyll content which, in turn, is closely associated with the nitrogen (N) content. Most of leaf N is contained in the chlorophyll molecules The CCM meters, also commonly referred to as SPAD meters, are popular with scientific researchers, students as well as growers to determine the chlorophyll content of leaves. Such measurements are required for water and nutrient stress, nitrogen management, as well as fundamental research on photosynthesis and plant physiology Chlorophyll is an indicator of crop health and productivity. Measuring chlorophyll is usually done directly and requires significant time and resources. Indirect measurement of chlorophyll density using a handheld portable chlorophyll meter can reduce time.
