CHLOROPHYLL METER
SPAD-502
A lightweight handheld meter for
measuring the chlorophyll content of
leaves without causing damage to plants.
The SPAD-502 is a compact meter
designed to help users improve crop quality and
increase crop yield by providing an indication of the
amount of chlorophyll present in plant leaves. The
chlorophyll content of plant leaves is related to the
condition of the plant, and thus can be used to
determine when additional fertilizer is necessary. By
optimizing nutrient conditions, healthier plants can be
grown, resulting in a larger crop yield of higher quality.
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.
Small measuring area
The measuring area is only 2 × 3mm, allowing
measurements of even small leaves. A sliding depth stop
is included for accurate positioning of sample leaves.
Quick, easy measurements
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.
High accuracy
High measuring accuracy (± 1.0 SPAD unit for rice-plant
leaves) allows close examination of growing conditions.
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.
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 in memory can be
automatically calculated.
Reading checker
A reading checker enables users to check that the SPAD502 is functioning correctly and providing accurate
readings.
