HandySpec Field®: Portable Spectrometer System

HandySpec Field is specifically designed
for the measurement of diffuse reflection
characteristics of plants and soil. The portable 2-channel spectral sensor system
has been used by several well-known scientific
institutes for years and shows superior

performance within this demanding environment. tec5 is also the
partner of
Yara GmbH & Co. KG in Dülmen for the development of the Yara N-Sensor, the tractor based
system for the site-specific N-fertilization.

HandySpec Field in China
The portable system consists of a measuring unit and
a sensor head, which is connected to the main unit
by flexible optical fibers. The main unit consists of
high-quality spectrometer modules from Carl Zeiss,
the tec5 operating electronics and an exchangeable
battery pack. The sensor head contains two input
windows with receiving optics. The measurement itself is controlled by a push button, located
on top of the sensor head.
The sunlight is used as light source for generating the
diffuse reflection of plants. As light intensity and spectral distribution varies a lot with changes of daytime
and clouds, the system is designed as a 2-channel
device. In this configuration a permanent referencing to present illumination conditions, synchronous to
measurement, is realized as a key feature.

Customer Statement
"Compared to conventional spectroradiometers,
t the instrument shows its advantages especially at changing cloud coverage conditions"
