Comparative analysis of standard frameworks
Comparison of technical requirements
- The normal working conditions of the instrument include the ambient temperature range (5~35°C), relative humidity not exceeding 80%, and power requirements (220V±22V, 50Hz±1Hz).
- The measurement range of the sulfur and nitrogen element analyzer is divided into gas, liquid and solid according to different sample forms, and the linear correlation coefficient of each range is r≥0.999.
Performance indicators and safety
- The temperature control range of the cracking furnace is from room temperature to 1100°C, and the temperature control indication error is ±5°C.
- The gas path sealing requires no leakage, and the flow stability changes within 30 minutes. No more than 2%.
- Safety requirements include clear markings, protective grounding and dielectric strength testing (1500V for 1 minute without breakdown).
