Mark...you are a true geek... And I mean that in the BEST possible meaning of the name!
You are awesome...and all of that is a bit overwhelming for me...lol. From now on...I will ask you to fill in the number gaps...lol.
Shaun...what you're looking at may work to a point depending upon how accurate the UVB sensor really is and how many zeros you accurately ad on... ;D. The meter most of us use that have them have been developed specifically for herp care. This is a gauranteed reading as long as the instrument has not been dropped or the batteries are still good.
Occasionally the meter may need to be recalibrated...especially if there has been an impact, but it is the best in many peoples opinion (including those who are testing UVB emitting lights for the lighting industry)...and going cheap with herp care just ain't kosher. Sometimes you just need to put up the $$ for what you know works best. Sufficient isn't good enough IMHO...
There is the Solarmeter 6.2 which is what I have, and the testers I had mentioned previously, use. It is normally $179.00. I have a friend who has worked out a discount price with the supplier for $135.00. This includes S&H.
She is working on one last order now I believe. I think Dom is trying to order one from her too from the UVB_Meter list.
The order will be going out in two weeks or less. Diane is the one who is taking the orders. I will give you her e-mail in a private message. Tell her Veronica gave it to you and you would like to place an order. She will require the money up front.
