A cost-effective thermopile pyranometer for accurate solar radiation measurement in PV and environmental applications.
| Datasheet |
Product Description
The LPS03 Pyranometer is designed for reliable measurement of global solar radiation, making it suitable for applications such as PV performance monitoring, meteorology, and environmental research.
Based on a thermopile sensing principle, it delivers stable and accurate measurements while meeting Spectrally Flat Class C requirements (ISO 9060). The sensor is factory calibrated and compliant with relevant standards for solar monitoring systems.
With flexible output options including Modbus RTU and analog signals, the LPS03 integrates easily into data loggers and monitoring systems. Its robust design, integrated leveling features, and optional tilt sensor ensure accurate installation and long-term reliability in outdoor environments.
Key Features:
- Spectrally Flat Class C pyranometer (ISO 9060 compliant)
- Measures global solar radiation up to 4000 W/m²
- Thermopile sensor for stable and precise measurements
- Available outputs: Modbus RTU, analog (4–20 mA / voltage), or mV
- Factory calibrated with individual calibration report
- Optional tilt sensor for installation monitoring
- Integrated bubble level and adjustable feet for easy setup
- Built-in diagnostic sensors (temperature, humidity, pressure) in digital models
- Rugged IP67 design for harsh outdoor environments
- Suitable for PV monitoring, meteorology, and research applications
Please refer to the table below for the technical specifications according to ISO 9060:

There are multiple output options available:
- Raw mV output
- 4-20 mA output
- MODBUS-RTU output
- MODBUS-RTU output with configurable analog output (e.g. 4-20 mA or 0-10 V)
