Automatic Polarimeter

An automatic polarimeter's specifications include its measuring range (typically ±90° optical rotation and ±259° Z for sugar), minimum reading (0.001°), accuracy (e.g., ±0.01° or better), and repeatability (e.g., 0.002°). It uses a consistent light source like an LED at a specific wavelength (e.g., 589.3 nm) and often features Peltier temperature control for sample stability, a user-friendly LCD or touchscreen display, and multiple measurement modes like optical rotation, specific rotation, concentration, and sugar degree.
