At Davos Instruments, we believe in creating long-lasting products. We strongly advocate repair. Many reference radiometers are successfully operated for 40 years and more. Whether they require major repairs or minor maintenance, we look forward to taking on the challenge.
In addition to the PMO8, Davos Instruments is also your official repair and maintenance partner for PMO6 radiometers of all generations. We also offer support for all other veteran reference instruments.
Driven by our intrinsic motivation to learn more about older radiometers, we have upgraded and maintained the PMO5/WSG radiometer, as well as some HF/AHF models, in the past.
Due to our proximity to PMOD/WRC, repairs can be conducted alongside a validation or calibration at PMOD/WRC at no extra shipping cost.
The PMO6 radiometer is a reference instrument used to measure direct solar irradiance. It was originally developed by PMOD/WRC in the late 1970s for total solar irradiance measurements from high-altitude balloons and satellites. Between 1980 and 2016, several versions of the PMO6 were built. The most recent PMO6 series was built in 2016 by Davos Instruments. The PMO6 is still widely used as a calibration reference for solar sensors.
The PMO6 can be upgraded with our Linard control unit. This allows you to maintain your existing reference while benefiting from a completely new control and data acquisition system, as well as a modern user interface.
In order for your existing PMO6 sensor to be upgraded, it will be integrated and tested in Davos with the new control unit so that an optimal system configuration can be guaranteed. Thanks to our proximity to PMOD/WRC, a calibration certificate for the new configuration can be obtained at the same time.
The in situ validation kit consists of a calibrated WRR PMO6/PMO8 system that can be leased on a monthly basis and returned once the validation process is complete.
In situ calibrations and validations are possible without the need to own such a reference instrument.
This procedure has several advantages over recalibration at a calibration facility:
