SC 4000是一种便携手握式的、多功能的油膜/润滑剂厚度测量仪器。其功能包括：开速的在线场或实验室测量输出/输入材料的油膜厚度；在自压制车间和钢或铝的轧钢厂的油膜厚度控制。

使用SC 4000进行测量时，您只需将本仪器放在金属表面并开启它就可。关于油料的信息将瞬间显示出来。测量的结果的数据将与用户信息和标样信息一起被存储在仪器内部的内存中。

报告的选项包括观测单元显示器上的测量统计，也能将本仪器所有的测量数据通过软件传输到电脑上，在微软的windows下显示报告。

SC 4000的适用范围十分的广：

冷轧钢厂钢处理生产线非铁的冷轧铝厂非铁的铝处理生产线酸洗线热浸镀锌线电解涂层线压制成形线钢材分配中心

The instrument is available in two versions, GS and AT:

GS version is optimised for pickled, electro galvanised and other mat substrates. AT version is designed for all other measurements, such as thin oil coatings on shiny substrates.这种仪器有两个版本可供使用，GS和AT：GS版是专门为酸（盐）渍的，电镀的以及其他人工顶板的基底而优化过的。AT版是专门其他测量而设计的，例如发光基底的轻油涂层。 Both models are provided with data transfer to PC and with Windows software package for reporting and calibration. SC 4000 main features:

Accurate and fast on-site measurements with a wide oil film thickness range. The measurement is fully non-destructive to oil film and substrate. Can be used for lubrication or corrosion protection oil films, dry lubricants or other organic coatings. 两种机型都能将报告数据和标样的数据传输至电脑，通过软件显示。SC 4000主要的特点是：快速精确的在现场测量油膜的厚度，并且测量的范围很广。测量完全不破坏油膜和基底。适用于润滑或防腐保护油膜，干润滑剂或其他有机酸涂层。

The SC 4000 has a unique method of ensuring reliable operation of the instrument. This patented method is based on the use of a reference plate containing a stable, permanent sample film. The user can easily check the response of the instrument against the reference plate.

For continuous online measurements Thermo Scientific offers an Online Oil Film Thickness Gauge that is based on the same infrared measuring principle.

SC 4000有一种独特的方法来确保此仪器处于可靠运算状态。这种取得专利的方法是基于使用包含稳定的永久的样品薄膜的基准样片。用户可以通过本基准样片很容易的检查仪器的响应。

对于连续性在线测量，热电电子还能提供一种基于红外线测量原理的在线油膜厚度测量仪。
