Pyranometer

Specifications:

• Absolute Calibration: Calibrated against an Eppley Precision Spectral Pyranometer (PSP) under natural daylight conditions. Calibration uncertainty under these conditions is estimated as ± 3% typical, within ± 60° angle of incidence.^*
• Sensitivity: Typically 75 μA per 1,000 W m^-2
• Linearity: Maximum deviation of 1% up to 3,000 W m^-2
• Response Time: Less than 1 μs (2 m cable terminated into a 147 Ohm load)
• Temperature Dependence: ± 0.15% per °C maximum
• Cosine Correction: Cosine corrected up to 82° angle of incidence
• Azimuth: < ± 1% error over 360° at 45° elevation
• Tilt: No error induced from orientation
• Operating Temperature Range: −40 °C to 65 °C
• Relative Humidity Range: 0% to 100% RH, Non-Condensing
• Detector: High stability silicon photovoltaic detector (blue enhanced)
• Sensor Housing: Weatherproof anodized aluminum body with acrylic diffuser and stainless steel hardware; O-ring seal on the sensor base
• Size: 2.36 cm diameter × 3.63 cm (0.93” × 1.43”)
• Weight: 24 g head; 60 g base and cable (2 m) with screws
• Cable Length: 2 m, 5 m, 15 m, 50 m (6.5’, 16.4’, 49.2’, 164’)
