    Hi there, i have a refractometer that does not auto compensate for temp. The question is can i simply recalibrate by using water with SG of 1.025 @ 20C (which it is currently calibrated at) and then raise the temprature to 25C and then test again and make adjustments ?

    Temp really does not play as big a role as everyone makes out. Unless the water is considerably colder/warmer (10 degrees) it will not make a noticeable difference. Just use normal RO water at room temp to calibrate it.
