Complete Guide to Handheld Refractometers – Types, Uses & Where to Buy
Whether you're measuring sugar in fruit, salinity in seawater, or glycol levels in automotive fluids, a handheld refractometer is your go-to tool for quick, accurate, and on-the-spot analysis. Compact, durable, and incredibly versatile, these instruments are essential across industries like food and beverage, agriculture, automotive, dairy, HVAC, laboratories, and aquaculture.
At Measurekart, we offer a complete range of refractometers to meet every professional need.
What is a Handheld Refractometer?
A handheld refractometer measures the refractive index of a liquid to determine its concentration. By placing a few drops of liquid on the instrument's prism, you get immediate readings of sugar content, salinity, alcohol %, or other critical properties. Most modern refractometers feature Automatic Temperature Compensation (ATC) for precision, even in fluctuating environments.
