The O3100 Column Oven incorporates PID subsection control technology for rapid temperature ramping with minimal overshoot, significantly reducing equilibration time. A high-precision temperature sensor combined with built-in calibration algorithms ensures accuracy ≤ ±0.3 °C and precision ≤ 0.1 °C. Comprehensive safety features include overtemperature alarm, short-circuit protection, and power-outage memory. The oven is fully controllable via RS485 communication using kromstation workstations. A user-friendly VFDS digital display provides clear real-time temperature readout and intuitive menu navigation. The highly integrated STM32 microcontroller with SMT packaging improves reliability and reduces board size.
