FAQ:
Q: How to calibrate marine salt refractometer for seawater?
A: Calibration liquid just get the Kirkland (Costco) bottled water that says distilled water (it’ll say with minerals for taste but that doesn’t affect the meter) and calibrate to 0.00. My meter came already calibrated to 0.00 so nothing more to do but to start mixing marine salt with distilled water and playing with the refractometer.
Q: How is a Refractometer used to determine salinity?
A: … refractometer is used for determining the salinity of various solutions. It has a rubber grip to prevent your body temperature from interfering with your results, and the eye piece’s scale is clearly defined. Instructions included.
Q: What kind of refractometer is used for specific gravity?
A: Handheld portable refractometer for salinity (0 to 100%) and specific gravity (1.000 to 1.070 ATC) measurement of seawater used in rinsing seafood or salt in cooking Automatic temperature compensation (ATC) for immediate and accurate readings, regardless of ambient temperature Unit displays in…
Q: Which is the best refractometer for sodium chloride?
A: First, is the Palm Abbe digital refractometer with scales for sodium chloride (NaCl). Scales are available for salt concentration as percent by weight, parts per thousand (ppt), or percent (%) saturation. There are also scales available for testing the freeze point of your brine solution.
