Met One- 10718 Solar Radiation Sensor

The Met One 10718 Solar Radiation Sensor is a precision instrument designed to measure solar irradiance in environmental, climate, and renewable energy applications. It features high accuracy, fast response, and durability for reliable long-term field deployment.

  • High Accuracy & Stability: Calibration uncertainty <3% at 1000 W/m² with long-term drift <2% per year.
  • Fast Response: Less than 1 ms response time, ideal for real-time monitoring.
  • Wide Operating Range: Works in extreme environments from −40° to 70°C and 0–100% relative humidity.
  • Broad Measurement Capabilities: 180° field of view, spectral range 360–1120 nm, suitable for ambient, environmental, and climate studies.

Description

The Met One 10718 Solar Radiation Sensor is a precision instrument designed for accurate measurement of solar irradiance in a wide range of applications, including environmental monitoring, climate research, and renewable energy studies. It operates on a 5–24 VDC power supply with minimal current draw and provides a highly sensitive output of 1.25 mV per W/m², allowing for precise detection of solar radiation up to 2000 W/m². The sensor offers excellent measurement repeatability (<1%), low long-term drift (<2% per year), and minimal non-linearity (<1%), ensuring reliable and consistent data collection over extended periods. Its fast response time (<1 ms) and broad field of view (180°) make it suitable for dynamic outdoor environments.

Built to withstand harsh conditions, the 10718 Solar Radiation Sensor operates across a wide temperature range (−40° to 70°C) and full humidity spectrum (0–100% RH), with a durable cable featuring a shielded twisted-pair design and santoprene rubber jacket. Its spectral range of 360–1120 nm, combined with a directional response of ±5% at a 75° zenith angle, ensures accurate solar measurements under varying sun angles. Compact and lightweight, this sensor is ideal for integration into weather stations, renewable energy projects, and climate research setups where precise and durable solar irradiance measurement is critical.
