EKO INSTRUMENTS CO., LTD. - Pyranometer MS-80 - Instruction Manual Ver. 3
1. Glass Dome, Diffuser
A glass dome creates a sealed environment for the detector and protects it against dirt and rain. The dome of
the EKO pyranometers is only transparent for radiation emitted by the sun. Hence they block the undesired
infrared radiation emitted by the Earth’s atmosphere. By the combination of the glass dome and the diffuser,
it improves the cosine response generated by the incident light from the entire hemisphere.
2. Sensor
The sensor (thermopile detector), which is the heart of the pyranometer generates a voltage signal that is
proportional to the solar irradiance. The sensor determines the majority of the measurement properties (e.g.
response time, zero offset B, non-linearity, sensitivity, etc.). MS-80 sensor varies less by aging due to special
construction.
3. Sunscreen, Sensor Body, and Level
MS-80, MS-80A and MS-80M have a sunscreen to prevent body temperature increase generated by direct
sun light. Weather resistant metal is used for the body, which has resistant against decrease of nocturnal
radiation and heat radiation, and rain and dusts. The integrated sprit level is used for setup and maintaining
the sensor in a horizontally levelled position.
4. Drying agent
Enclosed drying agents inside the sensor body keep the sensor inside dry, prevents condensation of humidity
inside of the glass dome. There is no need to replace the drying agents as they are replaced when sensor is
recalibrated at EKO.
5. Cable and Cable Connector
MS-80/ 80A/ 80M are shipped with a 10 meter long output cable as standard length*.
Durable materials are used for the cable and connector, and pin terminals are attached at the end of the cable
for easy connection with data logger terminal block.
*If longer cables, round terminals or fork terminals are required, please contact EKO Instruments or your
distributor. (Also see [7. Specification, 7-4. Accessories List] for optional items.)
MS-80U has a 3 meter long output cable already attached, and the leads of the cable are soldered.
