Chlorophyll Meter SPAD 502 Plus

SPAD 502 Plus Chlorophyll Meter / 081318123880 Features : * Compact and lightweight for portability. The SPAD-502 is small enough to fit in a pocket and is extremely lightweight ( only 225g) so it can be easily taken anywhere. * Quick, easy measurement. Measurements are taken by simply inserting a leaf and closing the measuring head. It is not necessary to cut the leaf, so the same leaf can be measured throughout the growing process. * Water-resistant. The SPAD-502 is water-resistant, so it can be used outside even in the rain. It is not immersible and should not be cleaned with water. * Low power consumption. The SPAD-502 uses LED light sources, resulting in extremely low power consumption. One set of two AA size alkaline manganese batteries can provide approximately 20, 000 measurements * Small measuring area. The measuring area is only 2 x 3 mm, allowing measurement of even small leads. A sliding depth stop is included for accurate positionning of sample leaves. * High accuracy. High measuring accuracy ( ± 1.0 SPAD unit for rice-plant leaves) allows close examination of growing conditions. * Data memory. The SPAD-502 has memory space for 30 measurements. Data in memory can be recalled or deleted at a later time, and the average value of all data memory can be automatically calculated. * Reading checker. A reading checker enables users to check that the SPAD-502 is functioning correctly and providing accurate readings The SPAD 502 Plus Chlorophyll Meter instantly measures chlorophyll content or “ greenness” of your plants to reduce the risk of yield-limiting deficiencies or costly overfertilizing. The SPAD 502 Plus quantifies subtle changes or trends in plant health long before they’ re visible to the human eye. Non-invasive measurement; simply clamp the meter over leafy tissue, and receive an indexed chlorophyll content reading ( 0-99.9) in less than 2 seconds. Assess nitrogen needs by comparing in-field SPAD readings to university guidelines or to adequately fertilized reference strips. Research shows a strong correlation between SPAD measurements and leaf N cotent. New features in the SPAD 502 Plus include: • Trend graphing stores and displays up to 30 measurements • Waterproof design
