Infralytic oil film thickness gauge
Product details
The German Infralytic NG-2 oil film thickness gauge is a portable instrument that uses infrared filtering technology to quickly and accurately measure the thickness of oil films on metal surfaces. This device can measure oil films between 0.2-6 g/m2 on metal surfaces of various materials. Widely used in industries such as metal production, processing, and final use.
Its working principle is based on Lambert Beer's law: when a parallel monochromatic light passes through an absorption cell (or gas, solid) containing a uniform absorbing substance, its absorbance (A) is proportional to the product of concentration (c) and thickness (b).
A=K·b·c
So, when the absorption tank is a mineral oil (or organic film) with a relatively fixed concentration, the thickness of the oil film can be calculated by measuring its absorbance.
The main technical parameters are as follows:
1. Measurement range: 0.01~9.99g/㎡, the optimal measurement range is 0.2~6g/㎡ (≈ μ m);
2. Measurement accuracy: 0.001g/㎡, repeatability deviation below 0.005g/㎡;
3. Size and weight: 335mm (height) * 128mm (diameter), weight 3.4kg
4. Channel: Preset 11 measurement channels corresponding to different materials and 1 testing channel (can be added according to user requirements or added by the user themselves, up to 32 channels).
5. Data storage: The built-in memory can automatically store measurement results and their corresponding surface materials, and can also store the user's conclusions for each piece of data. Currently, using the stack principle, it can cyclically store 500 records. Randomly equipped with installation software and data cables for connection and operation between devices and computers.
6. Self checking program: The device is equipped with a material board specifically designed for self checking, which is coated with a specific thickness and very stable oil film. After each startup or idle for 20 minutes, the self-test program will automatically start to ensure the correctness and accuracy of the device. Based on this self checking program, the device can automatically compensate for measurement deviations caused by changes in environmental factors.
