TBQ-2-B Pyranometer
TBQ-2-B
The TBQ-2-B is a pyranometer that measures total solar radiation, direct plus diffuse, across a spectral range of 0.3-3 μm using a wire-wound electroplated thermopile sensor, requiring no external power. It is supplied in the UK by MetSensor UK.

Frequently asked questions
What does the TBQ-2-B measure?+
Total solar radiation, combining direct and diffuse components, across a 0.3-3 μm spectral range.
How does the TBQ-2-B differ from the TBS pyrheliometer?+
The TBQ-2-B measures radiation from the whole sky (global radiation), while the TBS pyrheliometer measures only the direct beam from a narrow angle pointed at the sun.
Does the TBQ-2-B need a power supply?+
No, it is self-powered and requires no external power.
What output does it provide?+
0-50 mV analogue signal, or RS485 digital output.
