100IR employs an infrared source of specific wavelength. Multiple
channel versions are available. At the time of purchase the customer
may select which infrared wavelengths are required. Many possible selections
in the range of 700 to 1000 nM. With a 4-1/2 digit LED readout, measurements
are typically accurate within +/-0.02%. At the time of purchase,
the customer can select filters with the central wavelength and bandwidth
of his choice.
instruments feature an electronically chopped test beam for maximum accuracy
and independence from ambient lighting conditions. The Model 100IR
can accommodate samples up to 2.0 inches thick and can measure to the center
of a 12-inch wide sample. They are easy to use, stable in operation,
and provide highly reproducible readings. Like all Graham Transmissometers,
the Model 100IR is virtually maintenance free.
Graham Transmissometers operate in any normal ambient lighting condition.
. .no need to operate the instrument in a darkened room!
of Percent Transmittance (%T) are obtained automatically simply by inserting
the sample in the optical path. The user can readily make 6 to 10 measurements
of transmittance per minute. Like all Graham Transmissometers, the
100IR is virtually maintenance free.
use, the Operator simply sets Zero with the light path blocked, then sets
100% with no sample in the light path. Readings are therefore absolute,
with no optical standard required.
as simple as that!
