Fast-Response and Spectrally Flat, with unprecedented low zero offset, analog output, and a 5-year recalibration interval, the MS-80 is an ISO 9060:2018 Class A leader and the IEC 61724-1 compliant go-to option for scientific research, industrial applications, photovoltaic system performance monitoring and large weather monitoring sensor networks around the world.
The patented design of the MS-80 features an isolated thermopile detector. Hermetically sealed under a pure Quartz diffusor and housed within a compact single-dome, the diffusor allows all solar wavelengths through while ensuring that the total energy received at the detector level, including harmful UV irradiance, is substantially lower than usual.
Our design, and commitment to quality, means that the MS-80 is better than competing pyranometers, best in class for accuracy, speed and reliability for every application.
