请翻译发货人放置于集装箱内的随货温度计显示该集装箱内温度在运输期间也保持在零下25度左右设定温度。至于集装箱流水问题我们发现集装箱内部泄水孔塞子未塞我们猜测可能是外界高温潮湿空气在泄水孔发生冷凝而形成的冷凝水。

The temperature gauge placed by the shipper inside the container shows that the temperature inside the container remained at around minus 25 degrees Celsius (set temperature) during transportation. As for the container's water flow problem, we found that the plug of the internal drain hole was not sealed, and we suspect that it may be due to the condensation of humid and hot air from the outside at the drain hole.
