These capabilities include the relation of EMF and the heating current (temperature), the sensitivity of the element to CO2, the response and recovery time, the influence of humidity, the property of resistance to other gases and the stability in 30 days.

• 首先测试了管式元件的各项基本特性，包括输出电动势EMF值随加热电流（即温度）的变化关系以及元件对CO2气体的敏感特性、响应恢复特性、耐水性、抗干扰性以及30天内的稳定性。
