Heathrow Scientific Handheld Urea Refractometer

Our Handheld DEF (Urea) Refractometer features the largest, easiest-to-read scale available with clear, sharp figures, screen shading and incredible contrast. This significantly enhances overall precision, even when several different people use the refractometer. This Urea refractometer also comes with a rubber grip on the body, which blocks the transmission of hand heat to eliminate temperature errors.
