• DR15-A1

    Analogue spectrally flat Class B pyrheliometer, with heating

    DR15 pyrheliometer is an ISO 9060 spectrally flat Class B (old ISO classification “first class”) instrument. It replaces the models DR01, DR02 and DR03. DR15 is used in tracker-mounted operation, and offers analogue millivolt output. The instrument offer 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! Also take a look at the spectrally flat Class A DR20 Pyrheliometer, with a better temperature response than DR15.
    • ISO 9060 spectrally flat Class B
    • Heating at low offsets for high data availability
    • Low power consumption
    • Analogue millivolt output
    • Supplied with test report for the individual instrument

  • DR20-A1

    Analogue spectrally flat Class A Pyrheliometer, with heating

    DR20-A1 is a high-accuracy direct (normal incidence) solar radiation sensor, or pyrheliometer. DR20 pyrheliometer complies with the Class A specifications of the ISO 9060 standard. It has a better temperature response than DR15-A1, which is a spectrally flat Class B pyrheliometer. These instruments are used in tracker-mounted operation, and offer analogue millivolt outputs. DR-series pyrheliometers have superior window heating that leads to high data availability.
    • ISO 9060 spectrally flat Class A
    • Heating at low offsets for high data availability
    • Low power consumption
    • Analogue millivolt output
    • Supplied with test report for the individual instrument, including temperature response

  • DR30-D1

    Next level digital first class pyrheliometer

    Welcome to the next level in solar radiation monitoring! DR30 is a high-accuracy digital direct (normal incidence) solar radiation sensor. The scientific name of this instrument is pyrheliometer. DR30 complies with the first class specifications of the ISO 9060 standard and the WMO Guide. This next level pyrheliometer has superior window heating that leads to high data availability, and an internal tilt sensor to check tracker performance.
    • ISO spectrally flat Class A
    • Low power consumption: DR30 needs only 2 W to keep its window free from dew and frost
    • Highest accuracy and highest data availability, featuring heating at low offsets, and on-board tilt and humidity sensors
