Chlorophyll Content Meter NCCM-100 is a portable, handheld device also known as SPAD meter which is used to measure the chlorophyll content in a non-destructive way. It features silicone semiconductor photodiode sensors that measures at dual wavelength concentration. It helps in rapid and accurate measurements that directly corelates to the photosynthetic activity and the plant's health and condition. This pocket-size device is a fundamental instrument that is used for fundamental research on photosynthesis and plant physiology.
