In a favorable light and on the
sunny side, the Pyranometer finds an ideal place.
The determination of global radiation is carried out by means of
measuring the thermal differences. Numerous high-quality
thermo-elements are arranged on a black reception surface. The
spherical cap protects the device against cooling by wind and
dirtying. A levelling panel and shade collar guarantee optimal use
and a homogenous temperature inside the case.

that is how the highly precise albedometer measures incident solar
radiation as well as reflection radiation (short-wave) over many
different surfaces. Determination of radiation balance or separate
signal output of direct and reflective radiation are possible
without difficulties with this albedometer (albedo evaluation).
Two thermopiles are especially aligned to the same sensitivity,
thus guaranteeing exact results. Measurements are very reliable
because the glass dome and white screens protect the measuring
elements extremely well against wind and weather.

This is a two channel radiometer with a cosine-corrected head that is fully sealed and is suitable for permanent external mounting. It has a common light collecting area for both channels.
This sensor is most frequently ordered with filters for Red and Far Red light (660 and 730 nm). This being a nominal standard around which much research work has been done. However, any two filter wavelengths can be chosen between 400 and 1000nm.

The PAR Quantum sensor counts quanta falling between 400 and 700nm. Light in this wave band is that used by plants for photosynthesis and such light is often referred to as 'PAR' (Photosynthetically Active Radiation). The sensor is calibrated in units of 祄ol/m?sec. A 祄ol is the new name for the unit 礒instein, which is one millionth of Avagadro's number of quanta or photons.

The SKS 1110 Pyranometer sensor is probably the widest selling unit in the Skye Instruments' range of sensors, with units sold all around the globe. It offers a compact sensor for solar energy measurements and compares favourably with thermopile sensors, offering considerable financial savings. It gives much greater output than thermopile instruments, which, with its better temperature stability, makes it easier to use. The sensors are calibrated against precision reference thermopile pyranometers in natural light conditions. Although production checks are made using artificial sources, these sensors are calibrated for use in natural daylight conditions, and should not be used with artificial or filtered light sources

Individual light sensors, available individually or as a bar of 3 or 6 sensors, allow you to
measure site-specifi c areas. These hand-held sensors feature cosine correction, built-in levels, and mounting brackets for
stationary measurements. Light Bars are frequently used when measuring across a greenhouse bench.

Spectrum's sensor captures radiation between 400 and 700 nanometers.
Range: 0-2500 umol m2s1. Sensor drift is 1% per year and includes a built-in level. Accuracy is +/- 5%.

Quantum sensors measure light energy at the specific wavelengths plants actually
use for photosynthesis. Research indicates that older lux and foot-candle meters
could have error rates up to 45% when used to estimate light quantum available
for plant growth. Start taking more meaningful light level measurements yourself
with a low-cost Field Scout Quantum Meter.
The FieldScout Quantum Meters measure Photosynthetic Photon Flux (PPF) as µmol m-2s-1
for Photosynthetically Active Radiation (PAR) in the range of 400 to 700 nm.
Quantum meters can be used in the field, laboratory, above or below plants, in
growth rooms and greenhouses. The meter approximates radiation between 400 and
700 nanometers(PAR) as umol m-2s-1.

Plants use the Red/Far Red light ratio to
determine how crowded they are, and grow tall or full accordingly. Previously,
Red/Far Red measurement required expensive spectroradiometers or sensors, and
post-measurement computation. The Field Scout meter displays the Red/Far Red
ratio on the LCD screen, and with the push of a button, the 660nm and 730nm
readings.

Monitor critical UV radiation. This portable, hand-held meter measures the UV
photon flux in the wavelength range of 250 and 400 nanometers in units of
µmol m-2 s-1 (micromoles of photons per square meter per
second).
High levels of UV light can be detrimental to plants. Use this meter to
determine the UV filtering capacity of greenhouse shades and glass barriers.
Includes one 9-volt battery. (Image is of previous model meter)

Good times are coming when
sunbeams hit the precision-grinded glass sphere and the rays are
focused. The stronger the sun shines, the more intensive is the
focal point which leaves traces on the recording cards. Absolutely
self-sufficient, the sunshine recorder reliably measures
year-round the sunniest hours. The robust, non-corrosive, and
easy-to-use device is employed in northern as well as in southern
latitudes worldwide.
