1.周围空气温度不高于+40℃，不低于-5℃，并且24h内其平均温度不高于35℃。
1. The ambient air temperature shall not be higher than+40 ℃, not lower than -5 ℃, and its average temperature shall not exceed 35 ℃ within 24 hours.
2.大气条件：空气清洁，相对湿度在高温度+40℃时不超过50﹪；在较低温度时允许有较高的相对湿度，例如20℃时为90﹪，但应考虑到由于温度的变化，有可能会偶然地产生适度的凝露。
2. Atmospheric conditions: The air is clean, and the relative humidity does not exceed 50% at the highest temperature of+40 ℃; Higher relative humidity is allowed at lower temperatures, such as 90% at 20 ℃, but consideration should be given to the possibility of occasional moderate condensation due to temperature changes.
3.海拔高度不超过2000米。
3. The altitude shall not exceed 2000 meters.
4.本装置适应于以下温度的运输和储存过程：25℃55℃的范围之间，在短时间内（不超过24h）可达+70℃，在这些极限温度下装置不应遭到任何不可恢复的损伤，而且在正常的条件下应能正常工作。
4. This device is suitable for transportation and storage processes at temperatures ranging from 25 ℃ to 55 ℃, and can reach+70 ℃ in a short period of time (not exceeding 24 hours). Under these extreme temperatures, the device should not suffer any irreparable damage and should be able to operate normally under normal conditions.
5.如果上述使用条件不能满足时，应由用户和制造厂协商解决。
If the above usage conditions cannot be met, it should be resolved through negotiation between the user and the manufacturer.
6.当本装置使用海上石油钻井平台和核电站时，应另行签订技术协议。
When this device uses offshore oil drilling platforms and nuclear power plants, a separate technical agreement should be signed.
