The first transfer standard radiometer
at NIST was developed by one of us (Carol Johnson) in the 1990s to transfer SI-traceable radiance scales to the SeaWiFS project at NASA.
Physically, filter-detector radiometers
can present difficulties in production design verification for several reasons: (1) not enough instruments to effectively collect multi-point data for complex surfaces, (2) rollers and nips of printing and coating machines make instrument measurements impossible, or (3) parts are simply too small to practically locate instruments.
Checking an LED light with a curing radiometer
is not as important as it is with a halogen light if it is a corded unit.
The second radiometer
was mounted on the tractor's roll-over protection system and faced upward to measure irradiance.
will provide high-resolution data on land use and land cover, track natural disasters, and probe climate variability and hydrology.
SMAP's active radar and passive radiometer
instruments are designed to complement each other and mitigate the limitations of each measurement alone.
A methodology for using a calibrated filter radiometer
to measure and monitor the spectral radiance of calibration sources is described.
from one manufacturer can report significantly different UV data than another instrument from a different manufacturer.

How To Select a Radiometer
describes the different styles of UV monitoring choices and specifies which types benefit each application.
A new line of plastic capillary samplers, called "safeClinitubes," has been designed by Radiometer
America of Westlake, Ohio, to eliminate the risk of medical-staff injury and contamination sometimes associated with glass samplers while maintaining high performance standards.
Using a radiometer
with filtration to look only at a small part of the lamp's output surrounding that wavelength would provide enough specificity for successful monitoring of the exposure at the required wavelength.
