Kipp & Zonen SMP22x – High-End Pyranometer with Modbus
The Kipp & Zonen SMP22x is a digital high-end reference pyranometer for particularly demanding and highly precise measurements of irradiance in W/m².
The SMP22x combines an RS-485 Modbus® interface with high-quality quartz glass domes and an exceptionally broad spectral range. This makes it particularly suitable as a reference sensor for test laboratories, solar simulation systems, research, and demanding calibration and comparison measurements.
With a spectral range of 250 to 3,500 nm at the 50% points, the SMP22x covers a significantly broader range than the SMP10x. At the same time, it offers improved directional response and very low thermal influences.

The SMP22x is particularly suitable for high-precision reference and irradiance measurements.
Typical applications include:
- Reference measurements
- Solar simulation systems
- Irradiance test benches
- Test and calibration laboratories
- Automotive testing
- Material testing
- Research and development
- Comparison measurements
- Homogeneity measurements
- Automated measurement systems
The exceptionally broad spectral range and high directional accuracy make the SMP22x a high-end solution for applications with demanding requirements regarding measurement quality.
The SMP22x enables highly precise measurement of irradiance and transmits the measured values digitally via RS-485 Modbus®.
With a spectral range of 210 to 3,600 nm at the 20% points, the sensor is particularly suitable for broadband radiation measurements.
Typical measurement tasks include:
- Measuring irradiance in W/m²
- Measuring artificial solar radiation
- Measuring broadband radiation
- Performing reference measurements
- Characterizing solar simulators
- Recording irradiance distribution
- Determining homogeneity
- Documenting test conditions
The high-quality optics reduce directional errors and enable particularly precise measurements even at different angles of incidence.
The SMP22x is suitable as a high-quality reference sensor for the characterization and verification of demanding solar simulation systems.
During a homogeneity measurement, irradiance can be recorded at defined positions within the test area.
The measurement data can be used to determine, among other things:
- Minimum irradiance
- Maximum irradiance
- Average irradiance
- Local deviations
- Homogeneity of the irradiance distribution
The SMP22x is particularly suitable for test laboratories with high requirements for measurement accuracy, reproducibility, and traceability of irradiance measurements.
Via RS-485 Modbus®, the SMP22x can be directly integrated into modern measurement and automation systems.
Possible integrations include:
- PLC
- SCADA
- Data loggers
- DAQ systems
- PC-based measurement systems
- Test bench software
- Automated measurement grids
- Reference measurement systems
Temperature-corrected measurement data and individual cosine/directional response data support particularly demanding measurement applications.
BF Engineering supports the integration of the SMP22x into solar simulation systems, test laboratories, and high-precision irradiance measurement systems.
In addition to measurement technology integration, BF Engineering can also provide characterization, homogeneity testing, and calibration of solar simulation systems and irradiance test benches on request.
