With MV-01 ventilator & heater you can improve the data availability of the MS-80 pyranometer. The MS-80 with ventilator will extend the sensor maintenance interval period and assures the availability of Solar data when deployed in cold climate regions or desert environments. MV-01 is compatible with the MS-80, MS-60 and MS-40 pyranometers.

The STR-21G-S is EKO's new integrated measurement system to measure all Solar irradiance components (DNI / GHI / GDI).  The system is based on nowadays most advanced sensor and sun tracker technology, which provide the lowest measurement uncertainty in accordance with ISO 9060. 

The STR sun tracker is an established reference and was deployed to many research projects in the world including Antarctica. With the cutting edge MS-80 Secondary standard pyranometer and MS-56 First Class pyrheliometer the STR-21G-S system can be freely configured to measure the required Solar radiation components. Hence a cost effective solution can be created for each application.

As an option the MV-01 ventilator & heater can be used with the pyranometer to ensure data availability. The MS-56 pyrheliometer has a standard heated front window to avoid condensation, snow and ice.

The new MS-57 pyrheliometer was inspired by the latest development of the MS-80 pyranometer enabling a break through
 in unprecedented low thermal offset behavior and 
fast thermopile response. The MS-57 real time performance with combined low measurement uncertainty makes Solar Irradiance measurements more realistic. 

Compared to all other pyrheliometers in the market the MS-57 has improved long-term stability properties. Therefore, the recommended period of recalibration can be extended to 5 years, which is typically 2 years for other sensor models in the market. The long-term stability of the sensor responsivity is less than 0.5% in a period of 5 years which makes it unique. 

The ISO First Class pyrheliometer “MS-57” is a high precision solar radiation sensor which is well suited to be used as a reference instrument for precise and accurate direct solar irradiance measurements and routine operation on a solar tracker.

Unlike all other manufacturers, EKO pyranometer and pyrheliometer can be calibrated in accordance with ISO17025. ISO17025 accredits that the recipient organization has achieved the highest technical and managerial expertise possible. Since 2013, we have maintained our accreditation under ISO17025. Recently, we had the 5th round of audits and passed without any issue. The auditor even gave us high praise for the personnel and practices used by EKO.

EKOs new pyrheliometer MS-57 which will arrive to the market early 2017. First class remains first class even when the new sensor shows the best performance characteristics in its class.

EKO Instruments recently went to the NOAA observatory at Mauna Loa on Hawaii island (Latitude: 19.5362° North Longitude: 155.5763° West). Mauna Loa is a world-renowned research site for measuring solar radiation and atmospheric constituent concentrations. From aerosols to trace gases, NOAA and other institutions have installed a platform of  outstanding equipment and instrumentation used intended for long term monitoring. Long term data sets are critical to understanding the change in radiative effects these constituents are having on a changing climate. What makes Mauna Loa such a great site is the installation is above the planetary boundary layer (3397 masl), making it a perfect candidate for performing Langley calibrations. Langley calibrations make use of the sun as the source radiation signal with the high dynamic range seen over a wide range of air masses. Mauna Loa gives good opportunities for the calibration.

EKO’s primary goal of the trip was to perform this Langley calibration using each of our reference spectroradiometers (MS series 700, 701, 711, and 712). This calibration campaign will provide insight into possible improvements to our calibration processes as well as a wonderful opportunity to test new devices. With some additional work, we hope to provide a spectrometer based sensor for retrieving aerosol optical depth (AOD). These commercially available products would be a first instrument unlike sun photometers, the AOD values would be accompanied with high resolution spectrum data. All important information for understanding the radiative effects of changes in atmospheric constituents.
