How do I know if solar meter is correct????
Today at 11.30 the sun was out but not very strong the reading I got was 5.5.
I have tested Acadia mvb 80w at a distance of 13in 33cm and have a reading of 6.5 does this sound right?
The 5.5 is right for an outside reading. I use a 5 year old solarmeter 6.5 and get an outside reading of 5.4 and a brand new solarmeter 6.5R with a reading of 5.8. I have never taken a reading on an Arcadia mvb, but have tested many Powersun 80w mvb and never seen a reading that high at 13 inches. They usually produce a reading around 4. I have read where knowledgable people said that Arcadia produce more uvb, so that is probably a good reading on the bulb.
Thanks for your help. I have two adults and 3 baby Hermanns all houses separately. The mvb 100w and 80w are from last year I started using t5 last August and find them much better. I use t5 for babies only a couple hrs a day if and when needed. I'm loving t5 bulbs and solar meter 6.5r.
t5 at 36cm is reading 5.1. I was about to change all bulbs but now I can save money going forward.
Have read that I will need to calibrate the meter at some point when might that be and how?
The forum is a big help thank you.
They have to be sent back to Solarmeter for recalibration. I had the same question about when, so I bought a second unit for comparison. I felt that my older meter was reading a little low and after today's test found it is only .4 below the new unit.
