This isn't your average polarimeter - this semiautomatic model with touch screen operation makes optical rotation measurements seriously easy! It handles four different measurement modes: optical rotation, specific rotation, concentration, and International Sugar Scale (°Z) for sugar industry applications. The accuracy is impressive at ±0.02° for optical rotation and ±0.05°Z for sugar measurements, with resolution down to 0.005°. The 5.6-inch touch screen makes operation intuitive - no more fiddling with tiny buttons. It uses a long-life LED light source at 589nm wavelength that's way more reliable than old-fashioned sodium lamps. The built-in temperature sensor automatically compensates for sample chamber temperature, and it works with both 100mm and 200mm test tubes. Measuring range covers ±90° for optical rotation and ±130°Z for sugar scale, handling everything from simple educational experiments to quality control in pharmaceutical or food industries. The memory stores up to 100 data sets, and USB connectivity lets you transfer results to your computer. Whether you're working in sugar production, pharmaceutical quality control, chemical research, or educational labs, this instrument delivers professional-grade performance with modern convenience. The semiautomatic operation means consistent, reproducible results every time - perfect for when you need reliable data you can trust.
