Hukx Pyranometers SR30-M2-D1, SR20-D2 and SR15-D1 – High-Accuracy Solar Radiation Measurement

Hukx develops professional solar radiation sensors, including digital and analog pyranometers for photovoltaic (PV) performance monitoring, meteorological stations, climatology and solar-energy research. The SR30-M2-D1, SR20-D2 and SR15-D1 are designed to measure hemispherical solar radiation and provide reliable irradiance data for demanding outdoor applications.

Applications of Hukx Pyranometers

A pyranometer measures solar radiation received by a plane surface over a 180° field of view, with irradiance typically expressed in W/m². These sensors are particularly important for evaluating PV plant performance, calculating solar resources, monitoring meteorological conditions and supporting long-term solar-energy studies.

The SR30-M2-D1 is suitable for high-accuracy applications such as national meteorological networks and commercial/utility-scale PV monitoring. It is a spectrally flat Class A pyranometer with heating, ventilation and a tilt sensor.

Main Models

The SR20-D2 provides a measurement range of approximately -400 to 4,000 W/m², with calibration uncertainty below 1.2% (k=2) and an operating temperature range of -40 to +80°C.

Advanced Technology for Reliable Solar Monitoring

Hukx pyranometers use spectrally flat thermopile technology to provide consistent solar irradiance measurements across a broad spectral range. The SR30-M2-D1 incorporates Recirculating Ventilation and Heating (RVH™), helping improve measurement availability in challenging environmental conditions. Its tilt sensor also supports monitoring of installation orientation.

For industrial installations, the newer SR200-D1 demonstrates Hukx's focus on accuracy, electrical safety and long-term reliability, incorporating isolated RS-485 communication, internal humidity diagnostics, an earthing terminal and integrated surge protection.

Comparison of Hukx Pyranometer Solutions

The SR15-D1 offers <1.8% calibration uncertainty, a spectral range of 285–3000 nm, response time below 10 s, and Modbus RTU over 2-wire RS-485.
