Pyranometer with Integrated Dome Heating

MS-80SH Pyranometer with Integrated Dome Heating from EKO Instruments sets a new standard for industrial and research solar irradiance measurements.
It exceeds the specifications for ISO 9060 Class A pyranometers. Moreover, it offers the best value and performance in this high-accuracy instrument class.

Launched as an upgrade to the MS-80 series, it offers unmatched accuracy, speed, and reliability. In addition, its smart interface and multiple signal outputs offer versatility and ease of use in all applications in solar energy monitoring, meteorological research, and photovoltaic (PV) systems. MS-80SH features 1.4W high-efficiency solid state dome heating that prevents dew and frost build-up on the dome. This ensures accurate data in all climate conditions.

Why Choose the MS-80SH Pyranometer with Integrated Dome Heating?

The MS-80SH uses a state-of-the-art sealed sensitive thermopile sensor. It responds in less than 0.5 seconds at 95%, and under 1 second at 99%. The advanced sensor architecture minimizes zero-offsets. Therefore, it achieves the lowest values without the need for ventilation. Thanks to its fast response and virtually no zero-offsets, MS-80SH delivers accurate solar data even during rapid changes in irradiance and ambient conditions.

The low-power solid state heater is switchable via Modbus/SDI-12 interface. This helps minimize power consumption in battery-operated systems. Dome heating keeps the optics clean, mitigating dew, frost, or snow. Consequently, MS-80SH is ideal for remote sites as it reduces manual maintenance needs.

Advanced Features for Optimal Performance

Equipped with internal diagnostics sensors—temperature, humidity, tilt, and roll—the MS-80SH enables remote monitoring. This provides real-time insights and helps optimize system efficiency. It also minimizes maintenance for complex networks or hard-to-reach locations.

By using diagnostic sensors in solar monitoring, users gain significant advantages. These go beyond remote status monitoring and improve data processing and validation over time. Traditional sensors may only output irradiance. In contrast, diagnostic systems provide data on internal tilt, level, temperature, and humidity. These insights are crucial for early anomaly detection, minimizing downtime and reducing on-site inspections—particularly valuable for large networks or remote sites. From a data analysis perspective, co-located diagnostics enhance the ability to assess measurement quality and reliability. Without them, analysts must rely on modeling assumptions or external datasets. This can increase uncertainty and reduce trust in results. Diagnostic info allows context-aware processing, automatic error flagging, and improved filtering or corrections.

Over time, this results in more robust datasets, better performance assessments, and greater confidence in decisions. In short, diagnostic sensors boost efficiency and enable automated data validation workflows. This supports advanced asset management and predictive maintenance in modern PV monitoring systems.

MS-80SH provides 2 types of smart interface: Modbus 485 RTU and SDI-12. Both are widely supported by data loggers and SCADA systems.

The MS-80 sensor offers the highest long-term stability. That’s why EKO recommends a 5-year recalibration interval instead of the standard 2 years. This reduces long-term operational costs by minimizing downtime and labor.

Just like all EKO pyranometers, MS-80SH comes with a 5-year standard warranty.

Applications and Installation

We offer a wide range of mounting solutions tailored for Plane of Array (POA), tilted, and albedo irradiance measurements. This supports diverse solar monitoring needs. The MS-80SH meets and exceeds ISO 9060 Class A specifications. It also complies with the IEC 61724-1:2021 requirements for Class A monitoring, making it ideal for utility-scale PV plants, climatology research, and outdoor test sites.

Compact and lightweight, the MS-80SH allows for quick and seamless installation into existing PV plant structures or meteorological setups. It can be configured with accessories such as an adjustable tilt mount, albedo mounting kits, or a Rotating Shadow Band (RSB-02). These enable it to accurately measure GHI, POA, DHI, DNI, and albedo from a single sensor platform.

All EKO pyranometers, including the MS-80SH, are calibrated in an ISO/IEC 17025 certified laboratory, traceable to the World Radiometric Reference (WRR), ensuring high measurement confidence. The MS-80SH is designed to perform reliably across all climate conditions, offering long-term durability and reduced maintenance costs.

Custom configurations are available, including extended cable lengths, junction boxes, and integration with digital PT-100 sensors or reference cells, making the MS-80SH a versatile and future-ready solution for any advanced solar monitoring system.
