Digital Polarimeter is specifically designed for measuring the rotating substances. The automatic polarimeter has a built-in Peltier precise temperature control system, which can meet requirements for testing at constant temperature within a 10° - 50°C range. It operates under a working wavelength of 589.3 nm with automatic calibration tool calibrating from -45° to +45°. This unit comes with an 8-inch TFT color touch screen and uses a USB, RS232, VGA communication interface to export multiple files via PDF.
