Marine Depot Refractometer

[jim.l]

I just received the instrument and read the instructions. There are no instructions for offsetting the reading for temp. It only says must be calibrated at 68deg. Since I live in south Florida, there are about two days a Year that the ambient temp of my house is 68 degrees. How am I supposed to calibrate the instrument? Is there a procedure for say 77 degrees, or do I need to return it?

Thanks
