产品简介： 红水温度计可分为两种：
1. 酒精温度计，是利用酒精热胀冷缩的性质制成的温度计。在1个标准大气压下，酒精温度计所能测量的最高温度一般为78℃。因为酒精在1个标准大气压下，其沸点是78℃。但是温度计内压强一般都高于1标准大气压，所以有一些酒精温度计的量程大于78度。在北方寒冷的季节通常会使用酒精温度计来测量温度，这是因为水银的凝点是-39℃，在寒冷地区可能会因为气温太低而使水银凝固，无法进行正常的温度测量。 而酒精的凝点是-114℃，不必担心这个问题。
2.煤油温度计的工作物质是煤油，它的沸点一般高于150℃，凝固点低于-30℃。所以煤油温度计的量度范围约为-30℃～150℃。因酒精的沸点是78℃，凝固点是-117℃，酒精温度计能比煤油温度计测更低的温度，但高于78℃的温度它就不能测定了。
