We are pleased to announce that, as a result of constant growth and development, Hukseflux relocates to a brand new office with state-of-the-art production facilities. As of 10 June 2013, our new address is Delftechpark 31 in Delft, The Netherlands. Have a look at an impression of the new Hukseflux building by cepezed architects.

Intersolar 2013 starts June 19 in Munich, Germany. Hukseflux welcomes you to Booth B2.350.

Hukseflux Thermal Sensors introduces the new IR20 & IR20WS pyrgeometers. As a result of Hukseflux' technological innovation, IR20 is research grade and priced significantly lower than competing models of the same performance level. See IR20's specs and benefits or take a look at "IR20: The making of" (PDF).

The new SR20 secondary standard pyranometer is now available. This Hukseflux solar radiation sensor is of the highest category in the ISO 9060 classification system: secondary standard.
Our pyranometer selection guide assists you in choosing the right instrument for your application. See "SR20: The making of" and view SR20's unique features and specifications.

Hukseflux now offers the best calibration uncertainty. Together with PMOD Davos, expanded calibration uncertainty of Hukseflux' first class instruments has been improved from 3 % to 1.7 % (k = 2).
Results of benchmarking Hukseflux solar sensors by independent research are excellent as well. See the pyranometer & pyrheliometer comparison (PDF).

The ASTM workgroup G03.09 studies on uncertainty evaluation of measurements according to GUM with pyranometers and pyrheliometers.
Hukseflux has recently issued a spreadsheet to the workgroup for further review.

What instrument to use for the measurement of solar radiation in a PV plant? A thermopile pyranometer or a reference cell? This paper explains why thermopile pyranometers are the de-facto standard sensors for the measurement of solar radiation.
