Hand Held Brass Refractometer for Salinity 0-100

【𝑹𝒆𝒂𝒅𝒊𝒏𝒈 𝑺𝒄𝒂𝒍𝒆 0-100】: Our optical Brass refractometer has scales ranged from 0 - 100 ppt (0 - 10 %). The reading resolution is 1 ppt. It is designed for the measurement of seawater (marine aquaria) or very low concentrated salt solutions. The second scale is for reading of the salt solution density ranged from 1.000 to 1.070 g/cm3 (resolution 0.001 g/cm3). For Reference of solutions: 1.Fresh water < 0.5 ppt 2.Brackish water -- 0.5 to 30 ppt 3.Seawater -- 30 to 50 ppt 4.Brine -- 50 ppt.

【𝑴𝒆𝒂𝒔𝒖𝒓𝒆𝒎𝒆𝒏𝒕 𝑰𝒔 𝑬𝒂𝒔𝒚】: Place a few drops of the liquid on the optical part of the Brass  refractometer, cover the prism, and the liquid will spread more easily over the prism, look throught the eyepiece against the light and you will be able to read the result value on the scale. 10℃~30℃ / 50F ~ 86 F. For temperature beyond this range, please calibrate before use.
