EKO offers three different MS-80 pyranometer models each with different features. With this wide range of
sensors, EKO pyranometers can meet all possible application requirements, ranging from PV module
efficiency measurements to climatology research and material durability testing.
All MS-80 sensors give excellent durability. The sensor is airtight and can be deployed with little maintenance
since the desiccant is incorporated inside. Solar sensors are applied outdoors, hence the detector black
surface, optical components and sensor mechanics are constantly exposed to solar radiation, temperature
and pressure differences. UV radiation known as harmful radiation to materials can change the chemical
properties of substances irreversibly. In case of the MS-80 the detector it is totally isolated below the sensor
optics surface, which is sealed, and can’t be affected by a high dose of UV, moisture or pressure differences.
During production and inspection, the directional response and temperature dependency are measured and
validated through a measurement report that comes with each sensor. Besides, EKO provides a unique
calibration service for pyranometers compliant to the international standards defined by ISO/IEC17025 / 9847
[indoor method]. When an ISO/ IEC17025 calibrated sensor is purchased, EKO provides a calibrated sensor
with a consitently low calibration uncertainty. The Accredited lab is regularly re-examined to ensure that they
maintain their standards of technical expertise.
In case of MS-80, MS-80S, with combination of optional MV-01 [ventilator + heater unit], reduces the dew
condensation and accumulation of dusts and snow on glass dome by continuously blowing heated air. The
ventilation unit with heater is recommended when the sensor will be deployed with a chance of occurance of
condensation, snow and ice.
In the following paragraphs, the three instrument types are described individually.
1. MS-80
The analog MS-80 pyranometer can be used as a reference sensor to measure the global broad-band solar
radiation with a high accuracy in traditional sensor networks. With excellent temperature response and
non-linearity characteristics, it provides optimal performance throughout the day.
