"pyrheliometer" should NOT be redirected to this page. A pyrheliometer is an instrucment for measuring direct solar radiation (as opposed to total which a pyranometer does) and has nothing whatsoever to do with the content shown here. Plaasjaapie (talk) 14:59, 26 January 2009 (UTC)[reply]

I believe that, contrary to what is on the page as is, an actinometer does not measure the "heating power" (total energy content) of radiation. A bolometer measures that. I believe an actinometer measures the intensity (number of photons per unit time) radiation within a specified frequency range. Determining the total energy content would require accounting for the energy content of photons of different frequencies. — Preceding unsigned comment added by 2602:306:CFDD:6360:8D06:6569:BE02:7C77 (talk) 17:14, 7 April 2013 (UTC)[reply]

If the usage has changed from what ref 1 says, show us what ref has a better definition; or bring us a new source. We can't fix it just based on your belief. Dicklyon (talk) 17:42, 7 April 2013 (UTC)[reply]

Yeah, but how does it work?

Would someone add a description of exactly how the result is quantified? 12.33.223.211 (talk) 22:51, 2 April 2018 (UTC)[reply]
