Measures leaf chlorophyll, an important indicator of plant health.
The SPAD-502Plus performs quick measurements of the chlorophyll content of leaves without damaging the leaf. Its lightweight, splashproof design make it ideal for measurements in the field.
Introduction
Non-destructive measurement of plant chlorophyll
The SPAD-502Plus 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 optimize the timing and quantity of applying additional fertilizer to provide larger crop yields of higher quality with lower environmental load.
Features
Product Overview
Quick, easy measurement of chlorophyll levels in plant leaves without damaging the leaf.
Measurements are taken by just closing the measuring head on the leaf. Since the leaf is not cut off or damaged in any other way, the same leaf can be measured as the plant grows.
Trend graph display
Up to 30 measurements can be stored in memory and displayed on a trend graph, so that changes in measurements over time can be seen and abnormal values can be noticed at a glance.
Water-resistant
The SPAD-502Plus is water-resistant (IPX-4) so it can be used outdoors even in the rain.
*
It is not immersible, and should not be washed with water.
Compact and lightweight for portability
The SPAD-502Plus is small enough to fit in a pocket and weighs only 200g, so it can be taken anywhere.
Low power consumption
The SPAD-502Plus uses LED light sources, resulting in extremely low power consumption, with approximately 20,000 measurements from one set of fresh alkaline-manganese batteries.
Principal Applications
Monitoring of growth and health of plants
The SPAD-502Plus can be used to monitor the growth and health status of a wide variety of agricultural products, including wheat, rice, corn, cotton, etc.
Nitrogen fertilization optimization
The SPAD-502Plus can be used for determining when and how much nitrogen fertilizer should be provided to plants. Optimizing fertilization in this way leads to not only greater yields of higher quality, but also results in less over-fertilization, reducing environmental contamination due to the leaching of excess fertilizer into the soil and underground water.

Chroma Meter CL-200 of 日本
Handheld and lightweight instrument for color, illuminance and color temperature measurements.
Practically anything that illuminates can be measured with incident color meters. The possible uses range from research and development to production.
The CL-200 is a lux meter with a color function for workplace and street illumination, the production of lamps, or the measurement of very large surfaces and projectors (ANSI lumens) by taking advantage of the serial connection of several receptor heads.
The CL-200 is a replacement for two instruments - the CL-100 and XY-1- and includes many new features. Immediate measurement is possible from turning on the unit by quick automatic zero adjustment so it is always ready to move at the speed of light. Sometimes it is necessary to measure remotely for matters of safety or convenience so the CL-200 receptor can be separated and connected up to 100m away from the measuring body by LAN cable. An RS-232 interface is built in to allow connection to PC and connection to thermal printer is also optional should a printout of measured data be required for validation.
Features
Compact - hand-held, lightweight design
Portable - battery operated, receptor head can also be detached from the main body for remote measurements
User-friendly - low battery indicator, can be controlled by a PC, easily transfer data to Excel, and includes a calibration function
Simultaneous measurements - has the ability to determine illuminance, color temperature, chromaticity, dominant wavelength, and excitation purity of a light source
Ideal for white LEDs - can measure the chromaticity from the phosphor as well as inspect the final product
Multi-use - can be used for any light source, ideal for LEDs and OLEDs
LED ranking function - using the included software, users can rank measurements on a chromaticity chart for easy comparison
A single unit used for data display and key operations can be connected to as many as 30 receivers.
Automatic calibration
PC and printer access
PC-Software optional
