What is new at Hukseflux and where are upcoming events & conferences? Hukseflux exhibits at the major solar energy related conferences, and meetings related to surface energy flux measurements in climatology.


Hukseflux is ISO 9001:2008 certified and has a worldwide support organisation to offer you local support and calibration services. New are the Hukseflux representations in India and Brazil! Please choose the "select your region" tab to visit the website of our local offices.

Get to know SR20-D1. It is the most accurate digital secondary standard pyranometer available. SR20-D1 outputs irradiance digitally and uses the industry standard Modbus communication protocol over RS-485, ideally suited for the solar PV industry.

Interested why pyranometers are the standard for outdoor PV system performance monitoring? Our new white paper explains the advantages of a pyranometer over reference cells.

Hukseflux introduces the high-quality VU01 ventilation unit. It is designed for use with the successful SR20 pyranometer and IR20 pyrgeometer. VU01 ventilation unit has the smallest footprint and enables users in need of a ventilated instrument to attain the highest measurement accuracy, even in extreme climates.

Research institute C-WET chooses Hukseflux instruments for solar mapping India. This largest project to date involves a vast solar resource assessment network of 120 measurement stations equipped with Hukseflux pyranometers, pyrheliometers and pyrgeometers.

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. Take a look at an impression of the new Hukseflux building by cepezed architects. As of 10 June 2013, our new address is Delftechpark 31 in Delft, The Netherlands.

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 1.8 % (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.

ASTM is still looking for volunteers. See the workgroup's webpage.

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.
