热偶真空计和电离真空计通常用于低真空压力测量,如果使用它们时的空气混合物与标定时的空气混合物不同,则它们的读数与真实压力就会有差别。为了得到真实压力而转换真空计读数的方法是有的,但这些方法都比较复杂又不可靠。 现在,已研究出联合使用上述两种真空计的诺漠图,能迅 Thermocouple and ionization vacuum gauges are commonly used for low vacuum pressure measurements, and their readings differ from the true pressure if the air mixture at the time of use differs from the air mixture at calibration. There are several ways to convert vacuum gauge readings to get real pressure, but these methods are both complicated and unreliable. Now, has been developed using a combination of these two kinds of gauges Nuo Mo map, can quickly
