It only takes a few drops of liquid to work, and it’s employed in the agricultural, food production, industrial, and manufacturing industries. It works on the concept of refraction, which explains how light bends as it passes through two different mediums. WebA correction value of +1% when the prism cover is folded up. The corrected measurement result is therefore -1% + 1% = 0. A rule of thumb for temperature correction of refractometers with refractive index scales: Subtract 0.0001 to 0.0004 nD per °C with a device temperature of less than 20°, if the temperature is higher, add that number. script fonts for websites
