提出了对热处理用温度数字显示仪表进行环境试验的必要性,环境试验包括热冲击试验、腐蚀试验、振动试验、温度循环试验和高温高湿试验。并对不同温度测量仪表进行了可靠性环境试验及试验前后的误差测定,为仪表的可靠性提供了试验依据。 The necessity of carrying out environmental tests on the temperature digital display instrument for heat treatment is put forward. The environmental tests include thermal shock test, corrosion test, vibration test, temperature cycling test and high temperature and high humidity test. And the reliability of different temperature measuring instruments environmental test and test before and after the error was measured, providing the test basis for the reliability of the instrument.
