The BF3 privides three simultaneous electronic outputs,

giving total and diffuse radiation, and sun duration.

No routine daily adjustments are needed. Outputs can

be logged as energy (W.m-2), P.A.P. (μmol.m-2.s-1)

or illuminance (klux), and sunshine states.

The BF3 is an affordable alternative to the high

performance SPN1.

The Sunshine Pyranometer uses an array of seven thermopile

sensors under a computer generated shading pattern  to

measure the direct and diffuse components of incident solar

radiation.  A microporcessor derives global and diffuse

radiation values, and sunshine status.

The SPN1 is a patented meteorological class sensor designed

to be an affordable alternative to shade-ring pyranometers,

pyrheliometers, Campbell-Stokes and other sunshine recorders.

SunScan is optimised for low regular canopies such as most

agricultural crops.  The 1 metre probe permits rapid spatial

average averaging of large areas, and PAR mapping for non-

uniform crops such as vineyards and orchards, where LAI theory

doesn't apply.  With the unique BF3 reference PAR sensor,

SunScan is usable in most weather conditions.
