Chlorophyll Meter
Introduction:

• Measures leaf chlorophyll, an important indicator of plant health.The SPAD-502Plus performs quick measurement. Non-destructive measurement of plant chlorophyll
• Enables quick, easy measurement of the chlorophyll content of plant leaves without damaging the leaf. Chlorophyll content is one indicator of plant health, and can be used to optimise the timing and quantity of applying additional fertilizer to provide larger crop yields of higher quality with lower environmental load
• Quick, easy measurement of chlorophyll levels in plant leaves without damaging the leaf
• Optical density diff at two wavelengths
• 2mm x 3mm
• 1.2mm Max
• 12mm (with stopper having position adjustable from 01 to 6mm)
• 2 LED elements
• 1 SPD (silicon photodiode)
• LCD panel showing 4-digit measurement value (values shown to first decimal place) and 2-digit number of measurements; Trend graph of values in memory can also be shown
• -9.9 to 199 SPAD units
