For example, if the meter is set to a range of 300 V full scale, the meter's impedance will be 6 MΩ. 20,000 Ω/V is the best (highest) sensitivity available for typical analog multimeters that lack internal amplifiers. For meters that do have internal amplifiers (VTVMs, FETVMs, etc.), the input impedance is fixed by the amplifier circuit.
Late 1950s: Peak Flow Meter invented by Martin Wright (1912–2001), also the creator of the Syringe Driver. 1960 onwards: The hip replacement operation (in which a stainless steel stem and 22mm head fit into a polymer socket and both parts are fixed into position by PMMA cement) pioneered by John Charnley (1911–1982).
The two basic types with an analogue display are usually easier for the human eyes and brain to interpret, especially if many instrument meters must be read simultaneously. An indicator or needle indicates the measurement on the gauge. The other two types are only displaying digits, which are more complex for humans to read and interpret.

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.
Survey meters in radiation protection are hand-held ionising radiation measurement instruments used to check such as personnel, equipment and the environment for radioactive contamination and ambient radiation. The hand-held survey meter is probably the most familiar radiation measuring device owing to its wide and visible use.
Measuring combination of an automatic refractometer and a density meter as widely used in the flavors and fragrances industry Today's laboratories do not only want to measure the refractive index of samples, but several additional parameters like density or viscosity to perform efficient quality control.
A sphygmomanometer (/ ˌ s f ɪ ɡ m oʊ m ə ˈ n ɒ m ɪ t ə r / SFIG-moh-mə-NO-mi-tər), also known as a blood pressure monitor, or blood pressure gauge, is a device used to measure blood pressure, composed of an inflatable cuff to collapse and then release the artery under the cuff in a controlled manner, [1] and a mercury or aneroid manometer to measure the pressure.
