WebBenchtop and Portable Digital Refractometers. A refractometer (or brix meter), is an analytical instrument that uses a high-resolution optical sensor to measure the total reflection of a light beam that is in contact with a sample. The total reflected light is calculated and the refractive index value is displayed on the instrument, which can ... Web2 apr. 2024 · So it is difficult to locate faults by means of visual inspection. It is, however, feasible to locate such discontinuities via a test instrument known as the time domain reflectometer (TDR). The TDR is sometimes compared to a radar installation, the difference being that the medium involved is a transmission line rather than air or free space.
