The performance characteristics of Class A, B, and C sensorsestablished by the International Standards Authority in ‘ISO9060:2018’ are the primary method of comparing differentsensor classes and offer a helpful baseline when comparingsensors from different vendors.ISO 9060:2018 was introduced in 2018, with major changesfrom the previous classification standard launched in 1990.The new class definitions and criteria were designed to bemore consistent and compliant with available sensors, offeringa clear overview of classes and specifications to help defineselection criteria and support product comparison.With many products, including the MS-80 Class A pyranometerlaunched in 2016, EKO led the way, implementing design andperformance changes that would influence the 2018 standardand today help us produce the highest quality, most accurate,and reliable sensors in every class.

MS-80 Albedometer consists of two MS-80pyranometers and a special albedo kit with a glarescreen to measure the albedo with the lowestuncertainty.It is used in solar power plants with bifacial PVmodules and in meteorological applications.MS-80 is a unique pyranometer compliant to the "Fastreponse" and "Spectrally flat" sub-category under ISO9060:2018 Class A. The innovative patented designwas inspired by the combination of latest technologiesand state-of-the-art thermopile sensor, enabling abreakthrough in unprecedented low zero-offsetbehavior and fast sensor response.The compact sensor with a single dome, based on anisolated thermopile detector and Quartz diffusor isimmune to offsets and integrates all optionalvalue-added functions such as a ventilator, heater anddifferent industrial interfaces. The heater and ventilator
are suggested, particularly in areas impacted by dew,frost, snow, and dust.The MS-80A is an MS-80 with a built-in 4-20mAconverter and MS-80M with built-in MODBUSconverter. They are compatible with the industrialoutput standards. Due to the ultra-low temperaturedependency and exceptional non-linearitycharacteristics, the converter guarantees an optimalsensor performance, under any environmentalconditions.The MS-80 pyranometers are manufactured in aconsistent way followed by strict quality inspection andperformance evaluation. For each sensor, thedirectional response and temperature dependency aremeasured and validated through a measurementreport that comes with the sensor. EKO provides aunique calibration compliant to the internationalstandards defined by ISO/IEC17025/9847.

MS-60 Albedometer consists of two MS-60pyranometers and a special albedo kit with a glarescreen to measure albedo and total reflectance.It is used in solar power plants with bi-facial PVmodules and in meteorological applications.The MS-60 is an ISO 9060:2018 Class B (First class)pyranometer with analog output and improvedperformance. The new double dome constructionsprovides lower offsets and cosine errors.The MS-60 pyranometers are manufactured in aconsistent way followed by strict quality inspection andperformance evaluation. EKO provides a uniquecalibration compliant to the international standardsdefined by ISO/IEC17025/9847. The sensor has a5-year warranty with a 2 years re-calibration intervalrecommended and it is no longer necessary to changethe desiccant.

MS-40 Albedometer consists of two MS-40pyranometers and a special albedo kit with a glarescreen to measure albedo in routine applications.It is used in solar power projects with bi-facial PVmodules and in meteorological applications.The MS-40 is an ISO 9060:2018 Class C pyranometerwhich is based on the EKO's universal sensorplatform. It is the most cost-effective irradiance sensorto measure Solar irradiance across the full Solarspectrum. It can be used for agro meteorologicalnetworks and professional small scale PV sites wheresolar radiation is taken seriously.The MS-40 albedometers are manufactured in aconsistent way followed by strict quality inspection andperformance evaluation. EKO provides a uniquecalibration compliant to the international standardsdefined by ISO/IEC17025/9847.
The sensor has a 5 year warranty with a 2 yearsre-calibration interval recommended and it is no longernecessary to change the desiccant.

ML-02 Albedometer is a compact and cost-efficientsolution for measurements of reflected irradiance andalbedo. A special housing with a bubble level and70cm mounting rod makes it easy to use in anyapplication.The ML-02 sensor (ISO 9060:2018 Class C) is madefor light measurements in industrial environments. Thecompact dimensions of the sensor body make it easyto integrate within any application. Due to its lowweight and low profile, the sensor can be easilyattached to any light receiving surface. TheMono-Silicon detector with UV resistant diffuser givesa cosine response also at low solar elevation angles.Besides the effects of soiling or water deposition ontop of the diffuser will be minimized due to the coneshape geometry.The ML-02 detector has a high analog output and canbe combined with our industrial interfaces MC-11,MC-20, A-box and M-box to convert the signal to
