  • Product Name: RK200-08 Automatic Tracking Sun Direct Radiometer

RK200-08 Automatic tracking solar radiation measurement system is an unattended solar radiation monitoring system, which can accurately observe direct, scattered and total solar radiation at the same time. It use the Angle sensor and the four quadrant balance light sensor technology, automatic tracking the sun, the sun ray remain vertical to the radiation sensor within the cone of light. Track motion trajectory tracking system according to the sun and light way, the combination of 2D automatic control, realize a full automatic real-time tracking of the sun. Product from the base, bench, screw, gear box, motor, microcomputer controller, direct radiation sensor, scattered and total solar radiation, power and other parts.
The product is used to measure the direct and scattered solar radiation in the spectral range of 280 to 3000nm. It also can be directly measured sunshine time. It can be match RK600 series recorder.
It is widely used in photo voltaic environment monitoring, meteorological radiation observation, agricultural and forestry research and many other fields
