Features
Dome shaped sensor head (diffuser and body) facilitates runoff of dew and rain to keep the diffuser clean
Cosine-corrected for accurate readings even at low zenith levels
Rugged design for continuous outdoor use in all climates
Low-power operation and quick response time
Optional in-line connector (30 cm from sensor head) for
simplified maintenance
