A standard salt (brine) refractometer will therefore not give the correct salinity for natural sea water (NSW) and a conversion factor must be applied.\u003cbr\u003e\u003cbr\u003eFor example a 35ppt solution of NSW has the same refractive index as a 36.5ppt solution of brine.\u003cbr\u003e\u003cbr\u003eAfter extensive development, D-D’s new ATC refractometer addresses this issue as the scale is calibrated for seawater giving true salinity results for aquarium use when correctly calibrated and greater accuracy than previously attainable.\u003cbr\u003e\u003cbr\u003eOur refractometers feature a copper internal body which conducts heat faster than cheaper aluminium and plastic versions for faster and more accurate auto temperature compensation.\u003c\/p\u003e\n\u003cp\u003eEasier to Read\u003cbr\u003e\u003cbr\u003eOne of the other problems with most refractometers is that the scale displayed normally reads from 0-100ppt when we are really only interested in the region from 30-40ppt. Our new Seawater Refractometer has therefore been specifically designed to read from 0-40ppt which gives you 2.5 times the resolution of a normal 0-100 scale.\u003cbr\u003e\u003cbr\u003e \u003cbr\u003e\u003cbr\u003eAuto Temperature Compensation (ATC)\u003cbr\u003e\u003cbr\u003eThere is a lot of misunderstanding concerning the way the ATC feature works and its effect on the refractometer at different ambient room temperatures.\u003cbr\u003e\u003cbr\u003eSalinity is a measurement of a mass of salt in a mass of water and therefore does not vary with temperature however a refractometer does not measure salinity directly but measures the refractive index which is then displayed as salinity. The refractive index of a solution does vary with temperature therefore the reading that you measure with a refractometer is always temperature dependant.\u003cbr\u003e\u003cbr\u003eAn ATC refractometer has a bimetal strip inside the instrument that moves the reading scale as the temperature changes to compensate for the change in refractive index.
