Key features

RS-485 Modbus® communication
No change of desiccant for 10 years
5 year warranty (*)

The SMP6 has an internal desiccant that will last for at least 10 years. This minimizes maintenance significantly. The interval for dome cleaning can be extended, and the quality of measurements maximized, by fitting SMP6 with the CVF4 ventilation unit.

The SMP6 has a RS-485 Modbus® RTU interface, amplified analogue output, improved response time and temperature corrected measurement data. The wide and low power supply range from 5 to 30 VDC makes integration in meteorological and solar energy stations easy. The SMP6 is extreme robust and reliable and comes with 5 years warranty

Thanks to standardised output and connections of every SMP6, exchanging instruments for recalibration is easy. SmartExplorer Windows™ software for data logging, display of data and Modbus® address setting is provided as standard.
