即使糖的种类不同,只要浓度相同,它们各自的相对密度就会非常接近。相对密度是任何溶液的质量和同容积水的质量的比值,它随温度变化而变化,因此测定时必须校正温度。光线从一种介质进入另一种介质时会产生折射现象,且入射角正弦之比恒为定值,此比值称为折光率。果蔬汁液中可溶性固形物含量与折光率在一定条件下(同一温度、压力)成正比例,故测定果蔬汁液的折光率,可求出果蔬汁液的浓度(含糖量的多少)。常用仪器是手持式折光仪,也称糖镜、手持式糖度计,通过测定果蔬可溶性固形物含量(含糖量),可了解果蔬的品质,大约估计果实的成熟度。

工作时加热管完全浸泡于水中,依靠金属管优良的传导性迅速完成热交换,热效率高。不锈钢发热体和紫铜发热体的发热核心都是采用了上性能稳定的镍铬合金发热丝,不同的只是外面和内胆的材料不同。紫铜的特点:质软容易拉伸成型,耐酸性不耐碱性,由于我们的生活用水大多都是碱性水质(沿海地区碱性更大),所以容易氧化产生铜锈,高温发热时腐蚀更为严重,易被高温击穿,产生漏电。内胆承压能力差,高温易产生爆裂。不锈钢的特点:硬度比铜高,不易变型,耐碱性不耐酸性,由于我们的生活用水大多都是碱性水质,所以较不易被氧化。
