Secondary standard pyranometers

LSI LASTEM have designed the Secondary standard pyranometer as a Radiometer for solar irradiance measurement. The instrument is designed according to ISO 9060 and WMO No. 8 (Part I, Chapter 7) standards. These sensors are classified as ISO 9060 Secondary Standard.

These pyranometers benefit from high-end accuracy, reliability and a rapid response time.

First Class Pyranometers (direct output)

The First Class Pyranometers (direct output) by LSI LASTEM are also designed to meet ISO 9060 and WMO No. 8 (Part I, Chapter 7) standards.

These sensors are classified as ISO 9060 First Class.

This pyranometer is the best compromise between quality and cost in irradiance measurement, giving the user a a total daily uncertainty of 5%, flat spectral response (300-3000 nm) and optimal temperature stability.

First Class Pyranometers (analogue, RS485 output)

This type of LSI LASTEM pyranometer have different types of outputs compared to the DPA154, but the same features of measurement.

With an external converter for analog output, the model DPA854 has been built. The model DPA855 benefits from analogue output electronics that are mounted inside the sensor body.



The model DPA870, in addition to the radiation, measures the air temperature inside the sensor. Contact temperature can also be measured by connection to the DLE125 probe.

Second Class Pyranometers

Classified as ISO 9060 Second Class, this range of LSI LASTEM pyranometers are both more compact and lighter than the higher class pyranometers.

For basic meteorological, agrometeorological and solar energy applications, this pyranometer is very suitable.
