TENMARS TM-206 BTU Solar Power Meter

TM-206 Solar Power meter is ideal for the measurement of the solar radiation that is emitted by the sun from a nuclear fusion reaction that creates electromagnetic energy. 
The spectrum of solar radiation is close to that of a black body with a temperature of about 5800 K. About half of the radiation is in the visible short-wave part of the electromagnetic spectrum. The other half is mostly in the near-infrared part, with some in the ultraviolet part of the spectrum.

The units of measure are Watts per square meter or BTU, the typical test and measuring applications are:

  • Meteorology applications
  • Agriculture applications
  • Physics and optical laboratories
  • Solar radiation measurement.
  • Solar transmission measurement
  • Solar power research
  • Identify high performance windows
  • Helpful to set up Solar PV Panels at optimum angles of incidence
  • Light Intensity Measurement for the car windows
