SPAD 502 Plus Chlorophyll Meter

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 (-9.9 to 199.9) 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 content.

  • Instantly measures chlorophyll content or “greenness” of your plants on a scale of -9.9 to 199.9

Chroma Meter CL-200 

 

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

  • Leasing from ca. 59,00 Euro net monthly

C7000 LUX METER

 

Lighting solutions and applications have never been in greater demand and expansion as they are today. With the overwhelming popularity of these new light sources such as advanced LED and Organic Electroluminescence, the need to understand, manage and control these sophisticated illumination systems is essential. Manufacturing quality and process along with varying color and illumination qualities can often result in consistency issues. To address these lighting challenges, Sekonic Corporation, a leader for over six decades providing advanced precision lighting control for the Photo / Video / Cine industry has offered an ergonomic, intuitive Spectrometer, the SPECTROMASTER C-7000.

 

The new SPECTROMASTER C-7000 is a portable handheld spectrometer, designed especially for industrial use. Utilizing Sekonic’s CMOS linear image sensor design and software, the
