Hi,
I recently made up some calibration fluid, but unsure how to properly calibrate my ATC refractometer. My tank runs at 25c to 26c and my refractometer meter says 20c. Can I calibrate using the calibration standard of 25c?
Did a bit of light reading and still not certain if refractive index varies substantially to worry.
Can someone advice the steps to properly calibrate my refractometer at 20c should I be making a different calibration fluid. Also will this mean the calibration fluid must be 20c evertime I intend calibration. Does the refractometer at room temperature have any bearing on the calibration.
How will a 20c refractometer properly measure my tank considering its 25 to 26c.
