标准铂电阻温度计的正确使用与维护

Correct Usage and Maintenance of Standard Platinum Resistance Thermometer

标准铂电阻温度计属于精密计量器具,它精度高,稳定性好,可作为检定校准标准水银温度计、工作用玻璃液体温度计、工业热电阻、工业热电偶等的标准器。然而,其价格昂贵,制造工艺复杂,不耐震动,石英玻璃外保护管容易破碎。使用不当会出现数据漂移或损坏,标准铂电阻温度计的正确使用及维护是非常重要的。

The standard platinum resistance thermometer is a precision measuring instrument with high precision and good stability, which can be used as a standard instrument for calibration for standard mercury thermometer, generally- used glass liquid thermometer, industrial thermal resistance and industrial thermocouple thermometer. However, it is very expensive, with complicated manufacturing process, not resistant to vibration, with protective tube of quartz glass, which is easy to break. Improper usage may occur data drift or damage to it. The correct usage and maintenance of standard platinum resistance thermometer is very important.
