Refractometers measure the total soluble solids in an aqueous solution using light refraction method

Refractometers measure the total dissolved solids in an aqueous solution using light refraction method. The Refractive Index of a sample varies depending on its concentration and can be used to convert into many other useful units of measure. The digital Refractometers are highly accurate instruments that remove the subjective nature of traditional optical testers.  Manual (optical) refractometers offer users graduated lines on a scale used to reference the sample fluid, which is seen as a colour change. We stock a wide range of portable refractometers both analogue and digital, available in various scales for Brix (sugar), Refractive Index or hydration (specific gravity) measurement. We stock and supply the world famous Atago brand from Japan, including the popular PAL digital and MASTER optical series
