Middleton's EQ08 is a precision total radiation sensor used to measure global total radiation on a horizontal plane, and its performance exceeds internationally accepted high-quality radiation sensors. EQ08-S has an independent thermoelectric sensor inside, which has excellent low directional error, so it will not affect the model strength or response time. EQ08-S contains a built-in amplifier that can output a millivolt voltage signal for easy measurement.
