Our main solar energy measurement instrument is the Mk 1-G Pyranometer.

Sol-A-Meters are low cost, rugged, weatherproof solar radiometers intended for use under the most severe field conditions. They are completely self-contained and do not require any external power supply. All models incorporate the silicon photovoltaic cell as a sensor. Spectral response is from 0.35 to 1.15 µm. One hundred percent response to a change in signal takes less than one millisecond. All Sol-A-Meters are calibrated for the entire solar spectrum by comparison with thermopile type radiometers in bright sunshine on clear days. Cosine effect and air-mass effect corrections are made during calibration. Standard temperature compensation is from 40 to 140 °F. Each instrument is furnished with a certificate of calibration showing radiation in both English and Metric units.
Mk 1-G Solar Instrument

The Mk 1-G Sol-A-Meter is a weatherproof pyranometer (for total radiation from both sun and sky). Standard sensitivity is 50 mV per calorie/cm2·min. (2.5 or 5 mV per calorie/cm2·min. available upon request). Impedance is 1.0 Ω (0.05 and 0.10 Ω for 2.5 and 5.0 mV/calorie/cm2·min. respectively). Accuracy is ± 5%. The base is 5 inches in diameter. Shipping weight is 1-½ lbs. For full details, see the specification document <Click here>.

Key Features:
  • Rugged, low cost, elegant design.
  • Well matched material thermal properties.
  • Wide range spectral response.
  • Rapid response time: < 1 ms.
  • Low water absorption rate.
