Solar Spectrum Reflectometer Model SSR
(Click on the image for a larger view)
The Solar Spectrum Reflectometer, Model SSR-ER features a selectable air mass
solar measurement spectrum that maintains accuracy even for wavelength selective
surfaces. The SSR provides accurate measurements on both diffuse and specular
materials, even second surface reflectors up to 0.25 inches (6.4 mm) thick.
Solar reflectance or absorptance for air mass 0, 1, 1.5 or 2 is displayed to
0.001 units, with a repeatability of 0.003 units.
Key Benefits
 | Using the keypad on
the front of the electronics package, the operator can elect to display
reflectance or absorptance for the selected air mass solar spectrum.
Reflectance or absorptance for any one of the four individual detectors can
also be displayed. |
| Calibration and
adjustment of the measurement spectrum against one of the supplied standards
is accomplished with a single key stroke. Calibration data for up to five
additional standards can be saved in memory, permitting the use of working
standards other than those supplied. |
| A 'hold' function that
freezes the current reading, can be initiated from the keypad or a push button
on the measurement head. This is useful for applications that require the
measurement head to be handheld. It also allows reflectance or absorptance for
different air mass numbers to be displayed for a single measurement. |
| For quality control or
other routine measurements, a 'lock in' mode can be entered via the key pad.
This prevents inadvertent changes in air mass or detector selection. In
addition, if power is lost, the settings and calibration data are retained in
battery backed up memory and are restored on power up. |
