Features
-
Secondary standard Pyranometer
- Fast
Response time (95% < 5s)

Temperature compensated in a wide temperature range
- High
quality optical glass domes for proper cosine
reponse
-
Ventilation system to prevent any possible influence
of frost, snow and dust.
The Secondary Standard Pyranometer is the ultimate
reference sensor to measure global solar irradiance with
the highest precision. Its robust brass mechanical
construction makes it a durable sensor suitable to be
used in harsh environments. The MS-802 is used as
standard for PV research and climatology studies around
the world.
In combination with a Sun tracker (STR-series) or manual
shading ring (RSR-01), respectively the Global Normal
Incidence (GNI) and Diffuse (DHI) irradiance can be
measured. The MS-802F is a MS-802 with integrated
ventilator unit to improve the performance under various
environmental conditions (prevents or minimizes the
effect of dew, rain, snow, ice and dust).
