Ideal for checking thermal efficiency

• Measures and displays solar power intensity in units of W/m2 or Btu/(ft2 x h)
• Wide spectral range
• Uses silicon photodiode and cosine angular correction
• Min/max/avg memory + data hold
• Stores 99 readings

This meter displays four digit readings on a large LCD screen. Its wide spectral range offers accurate solar energy measurements using a silicon photovoltaic detector. Select either W/m2 or Btu / (ft2 x h) units. Additional features include data hold, minimum/maximum/average values, and auto-off. Includes four AAA 1.5V batteries, tripod mounting screw, and carrying case.
