Handheld refractometer, analogue ORA series Laboratory, ORA 4RR

Widely applied in chemical workflows, the handheld refractometer, specifically the ORA 4Rr model within the analogue category, serves as an essential tool for measuring the refractive index of various transparent substances in their liquid state. This device features a scale that's meticulously calculated and verified, ensuring precise measurements with exceptionally thin and clear lines. Its application extends to universal use, making it suitable for tasks requiring an extra large measuring range. Despite not having automatic temperature compensation, it can accurately measure temperatures between 20°C and 30°C without it. The ORA 4Rr comes complete with a calibration solution and storage box, making it a reliable addition to any laboratory setting.
