2.High Precision, stable and reliable temperature control system
The main control circuit uses advanced microprocessors, large-capacity FLASH and EEPROM memory, for more reliable preservation of data. The integrated design of measurement, control and electrical source in the circuit board improves the anti-interference and reliability of the instrument.
using the temperature control circuit of microprocessor, the temperature precision of the controlled objects in each heating zone reaches 0.1 degree precision.
The column box has double overtemperature protection. Once the temperature beyond the setting, the instrument will stop heating, and report the fault on the display.
Intelligent double back door technology ensures that the instrument can have good temperature control accuracy even when the temperature of the column box is close to room temperature, and can quickly cool down.
Temperature rise program of eight orders is suitable for the analysis of complex samples with wide boiling point.
