Skye Instruments are world renowned
for the design and manufacture of high
quality light and radiation sensors for
both indoor and outdoor use. Since
1983 much development time has
been invested to produce sensors
which meet expected and published
spectral responses, and all are
individually calibrated and traceable
to National Standards (National
Physical Laboratory, UK)
The 4 line LCD display presents
readings from up to 8 sensors or
channels simultaneously by freezing
the display and scrolling as necessary.
These measurements can be either
direct sensor measurements or ratios
between pairs of sensor channels, e.g.
for comparing light levels inside :
outside; above canopy : below canopy;
above surface : underwater; incident :
reflected etc.
The SpectroSense2 meters have been
designed specifically for recording
accurate light and radiation
measurements, even at very low light
levels. They are compatible with
Skye's own extensive range of sensors
plus those from other manufacturers.
Sensors are easily interchanged and
the meter's memory has storage for up
to 16 calibration factors. Connected to
several multi-spectral sensors, the
SpectroSense2 meter is ideal for use
as a low cost mini spectroradiometer.
Updated 10/10/07
Integration of light measurement over
time is also available, e.g. to give
daily values of MJ/day solar energy,
plus automatic datalogging of all
channels. Free software is included to
download the SpectroSense2+
memory to a PC. Datafiles are simple
ASCII format for direct use with
Excel, Word etc.
The range of Skye sensors for use with
the SpectroSense2 meter include PAR,
red/far-red, total solar radiation, lux,
UV and also custom wavelength to
order. Please ask for details.
