CHNSpec DS‑P900T Series Automatic High‑Speed Polarimeter DS-P500/P700T/P900T Lab Optical‑Rotation
CHNSpec DS-P500 / DS-P700T / DS-P900T Automatic High-Speed Polarimeter is a fully automatic high-precision optical analyzer for pharmaceutical, chemical, food, sugar, and research quality control applications. Adopting an LED light source with high-precision interference filters to output the 589 nm sodium D spectrum and integrated with multi-point automatic calibration technology, the instrument enables fast and accurate measurement across multiple modes including optical rotation, specific rotation, concentration, sugar content and user-defined parameters. It delivers a full-scale response speed up to 8°/s, completing 6 measurements in an average of 26 seconds. All models come standard with a 10.1-inch IPS capacitive touchscreen and Linux embedded operating system, supporting LIMS system integration. Featuring 128GB large-capacity storage, storage for up to 1500 measurement methods, user hierarchy management, electronic signature and data traceability functions, it balances high precision and high efficiency while ensuring data compliance, making it an ideal choice for QC testing in modern laboratories.
