    A typical water meter register showing a meter reading of 8.3 gallons. Notice the black "1" on the odometer has not yet fully turned over, so only the red hand is read. Water meters connected to remote reading devices through three-wire cables. There are several types of registers on water meters.

    Gemstone refractometers are available both as classic optical instruments and as electronic measurement devices with a digital display. [3] In marine aquarium keeping, a refractometer is used to measure the salinity and specific gravity of the water. In the automobile industry, a refractometer is used to measure the coolant concentration.

    They are also possibly the easiest device to use for measuring the refractive index of solid samples, such as glass, plastics, and polymer films. Some modern Abbe refractometers use a digital display for measurement, eliminating the need for discerning between small graduations. However, the user still has to adjust the view to get a final reading.

    Reading 46 °Oechsle. A traditional handheld refractometer is an analog instrument for measuring a liquid's refractive index . It works on the critical angle principle by which lenses and prisms project a shadow line onto a small glass reticle inside the instrument, which is then viewed by the user through a magnifying eyepiece.
