B 5.7 Carter-Scott Design Middleton SP01 Sunphotometer

The SP01 version has fixed field stops and operates in sun photom eter mode only.

• Four narrow-bandwidths measured simultaneously

• Detectors and filters held at constant temperature to enhance stability

• Low- noise signal amplifiers with negligible zero offset drift

• Three gain selections accommodate a wide range of signal strengths

• Motorised field stop on SP01-A can pause for signal zero check

• Weather-proof aluminum housing
