Product description

The PCE-SPM 1 solar radiation meter is the optimal device for solar engineers, architects and those working in the field of solar engineering. This solar radiation meter will measure solar power. Parameters such as current and voltage can also be measured with an optional multimeter with data logger device. This allows the user to take measurements over extended periods of time to determine the compilation and layout of a photovoltaic system.

Light intensity is measured using a silicon crystal. The integrated processor in the solar radiation meter is responsible to make automatic corrections to ensure accuracy after calibrating each device in the solar simulator. The most important parameter is Ptot (in W/m²) and can be seen clearly on the display.

Data saved in the internal memory (32,000 readings) can be transferred to a computer by way of software and cable connection. This solar radiation meter has been developed for the use outside and is made of a durable enclosure that is weather resistant. Its compact design makes it an ergonomic device.

  • Measurements of solar energy can be taken in situ, power output/ insulation: Ptot
  • Measurements can be taken over periods of time thanks to the internal memory for up to 32,000 readings
  • Software to analyse and transferring data is included
  • Possibility to make a comparative solar measurement
  • Minimum, maximum and data hold functions
  • Powered by 4 lithium-ion batteries for approx. 16 days of continuous use


PCE-SPM 1 solar radiation meter, internal sensor, RS-232 cable, software, 4 batteries, carrying case and user's manual.

Optional accessories:

ISO laboratory calibration with certificate for companies that wish to include this device in their set of internal testing tools or for annual recalibrations. The certificate meets the ISO 9000 standard and includes a laboratory calibration and a control document with all the measurement values.


The radiation meter can be mounted upon a tripod and positioned to take measurements over a period of time. There is a mini tripod included in order to place it on table tops. This optional tripod is much larger.

Multimeter with memory

This solar radiation meter can be converted into a multimeter. With data from both functions, calculations can be made to analyse the conditions of a photovoltaic installation.
