DR30 next level digital spectrally flat Class A pyrheliometerThe all-digital DR30-D1 pyrheliometer offers the highest accuracy and highest data availability, featuring window heating at low offsets. At the same heating power, the heating has been improved with a factor 4, at a 4 times lower offset! DR30 also offers on-board tilt and humidity sensors. It is applied in high accuracy measurement of the solar radiation received by a plane surface from a 5 ° full field of view angle. This quantity, expressed in W/m², is called “direct” solar radiation or DNI (direct normal irradiance). It is necessary to keep the instrument pointed at the sun by using a two-axis tracker. |
 |
Heated for high data availabilityHigh data availability is attained by heating of the front window. This suppresses dew and frost deposition. |
 |
Remote sensor diagnosticsIn addition to solar irradiance, DR30 outputs sensor diagnostics such as:
Remote diagnostics permits real-time status monitoring, reducing the need for (un)scheduled field inspections. |
 |
For communication between a PC and DR30, the Hukseflux Sensor Manager software is included. It allows the user to plot and export data, and change the DR30 Modbus address and communication settings. Also, the digital outputs may be viewed for sensor diagnostics. |

Using DR-series pyrheliometers offer significant benefits over the use of competing models. The all-digital DR30 pyrheliometer offers the highest accuracy and highest data availability, featuring heating at low offsets, and on-board tilt and humidity sensors. The advantages of having a heater and a tilt sensor are demonstrated in the DR30-D1 brochure (PDF). |
