热处理用温度数字显示仪表的可靠性环境试验

Reliability environment tests for temperature digital instrument used in heat treatment

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。

Necessity of the environment tests for temperature digital instruments was put forward,including thermal shock test,corrosion test,vibration test,thermal cycle test and high temperature high humidity test.The environment tests were carried out on the different temperature instruments and their errors were measured before and after environment tests.The test results offer the experimental proofs for the reliability of the temperature instruments.
