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. -
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

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

PMF01 is a practical metal bracket that helps mounting pyranometers on a vertical mast, horizontal crossarm, flat wall or a fence. It allows for horizontal as well as tilted (Plane of Array) orientation. The use of PMF01, compatible with all Hukseflux pyranometers, is easy. Its spring-loaded central bolt allows easy mounting and leveling. With its small footprint, in particular when combined with small footprint pyranometers such as SR30, PMF01 reduces problems with snow build-up; snow will simply drop off.- Quick installation
- Easy levelling using spring-loaded bolt
- For mounting pyranometers on horizontal and vertical tubes, on platforms, both horizontal and in Plane of Array
-
Model PMF02 enables a setup of two pyranometers, of which one in Plane of Array (POA), mounted to a frame or fence; ideal for PV system performance monitoring according to the latest IEC standards. PMF02 is compatible with all Hukseflux pyranometers.- Ideal for PV monitoring
- Quick installation
- Easy leveling using a spring-loaded bolt
- For mounting two pyranometers to a frame or fence, one horizontal and one in Plane of Array (tilted)

SHR02 is a shadow ring, used in combination with a pyranometer to form a "diffusometer". The ring will prevent direct radiation from reaching the pyranometer from sunrise to sunset, so that the shaded pyranometer measures diffuse radiation only. SHR02 is used with Hukseflux pyranometers such as SR30 and SR20. These models have very low zero offsets, leading to higher accuracy diffuse measurements than attained with competing models. SHR02 is compatible with most Hukseflux pyranometers. Hukseflux pyranometers have very low zero offsets, so that the diffuse radiation measurement has a better uncertainty than that of competing pyranometer-shadow ring diffusometers. To avoid problems with dew and frost deposition, the user should consider using the heated SR25 or the heated and ventilated SR30 pyranometer.- Relatively small size / light weight
- Low-investment alternative for a sun tracker with shading-disc
- High accuracy when used with Hukseflux (low zero-offset) pyranometers
- Save costs on expensive external ventilation; compatible with SR30 with internal ventilation
