MS-80 Pyranometer

MS-80 Pyranometer

Features

  • ISO 9060 Secondary standard
  • Fastest detector response
  • Quartz diffusor technologie
  • lowest temperature coefficient
  • Lowest offsets A and B
  • Industrial sensor outputs
  • 5 years warranty and recommended recalibration
EKO’s new generation sensors broke with the rules of traditional pyranometer architecture. The innovative patented design was inspired by the combination of latest technologies and state-of-the-art thermopile sensor, enabling a breakthrough in unprecedented low zero-offset behaviour and fast sensor response.
 
The compact sensor with single dome, based on a isolated thermopile detector and Quartz diffusor is immune to offsets and integrates all optional value added functions such as a ventilator, heater and different industrial interfaces. The heater and ventilator are suggested, particularly over areas impacted by dew, frost, snow, and dust.

The MS-80A is a MS-80 with built in 4-20mA converter and MS-80M with buit in MODBUS converter are compatible to the industrial output standards. Due to the ultra low temperature dependency and exceptional non-linearity characteristics, the converter guarantees an optimal sensor performance, under any environmental conditions.  

The MS-80 pyranometers are manufactured in a consistent way followed by strict quality inspection and performance evaluation. For each sensor the directional response and temperature dependency are measured and validated through a measurement report that comes with the sensor. EKO provides a unique calibration compliant to the international standards defined by ISO/IEC17025 / 9847. 

The sensor has 5 years warranty, 5 years recommended re-calibration interval and no longer need to change the dessicant.
