Salinity readings on refractometer Vs Reefangel controller salinity pr

[kraken]

Hi All,

I am getting very different readings for salinity for both devices

1) refractometer (calibrated at room temp, not 20 deg)

2) reef Angel controller salinity probe (calibrated with salinity calibration fluid)

the values I am getting defers by quite a bit, say 0.02/3 pts

for example one would read 1.025 while the other would read 1.023

which do you think is the problem and which method is the most accurate here?

Hi bro , I guess most pple use refractometer as a general guide .

I myself Use a refractometer .

Use DI water to test out both equipment and see which one gives a more accurate result. then calibrate the device you have.
