The Model 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. 

The 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.

All Graham Transmissometers operate in any normal ambient lighting condition. . .no need to operate the instrument in a darkened room!

Operation
Measurements 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 Model 100IR is virtually maintenance free.

Calibration
In 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.

It's as simple as that!
