Instrument Performance Specifications
   Measured Wavelength:         
   Search Logic:      User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria.
   Accuracy:       Measurement accuracy, expressed in +/- % of actual value will be measured and recorded.  Smaller values therefore represent better accuracy. 
   Search Logic:      All matching products will have a value less than or equal to the specified value.
   Spectral Sensitivity:         
   Search Logic:      All matching products will have a value less than or equal to the specified value.
   Instrument Type:       
   Your choices are...         
   Pyranometer       Global Solar Radiation (Sun + Sky): Daylight Radiation 
   Radiometer       Net Radiation Level (Sum of the incoming direct beam and diffuse solar radiation minus reflected solar radiation.)

   Other       Other instrument type not listed. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Technology Type:       
   Your choices are...         
   Thermopile       A thermocouple array connected to provide electrical output proportional to absorbed radiation.  Thermocouples may be connected in series for higher voltage output, or in parallel for higher current output. 
   Photovoltaic Detector       Photovoltaic cells measure radiation by generating a potential at a junction between two materials.  Also known as barrier-layer cells or detectors. 
   Other       Any unlisted radiation detection technology. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

Dimensions & Mounting
   Mounting:       
   Your choices are...         
   Base Mounted       Device is meant to be situated on a flat surface, such as a roof or designed stand. 
   Pole-mounted (Typically via clamps)       Device is designed to be secured via clamps to an elevated pole. Typical for weather stations where multiple components are monitored. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Height:       Height (Measured from mounting base to top of device) 
   Search Logic:      All matching products will have a value greater than or equal to the specified value.
   Weight:       Weight provides a rough estimate as to the size of the instrument being specified. 
   Search Logic:      All matching products will have a value greater than or equal to the specified value.
