Davis Solar Radiation Sensor 6450

Very sensitive. Readings seem a little high

This requires the bracket to enable it to be fixed to the ISS. The unit needs to be level to aid in it's accuracy. There is a spirit bubble in the housing but unfortunately shoddy workmanship has adhered the bubble at an angle making it useless. I was able to get the product level using other means. Compared to other sites, readings seem quite high, occasionally exceeding 1200wm². I would have thought 1000 to 1100wm² would be more realistic. Overall I'm happy but could be better for the money.
