What is the difference between a coating and film thickness gauge?
What is the difference between a coating thickness gauge and a film thickness gauge? Film thickness gauge and coating thickness gauge are the same product, with different names, just like gloss gauge is commonly referred to as glossmeter, glossmeter, or gloss tester.
Film thickness gauge is generally the same type of product as coating thickness gauge.
A film thickness gauge is generally used to measure the thickness of the oxide film layer, commonly used for aluminum based and copper based oxidation. When measuring, an N (non-magnetic) probe is selected for the coating thickness gauge, which is also known as a film thickness gauge for measuring aluminum based and other oxide layers.
Under normal circumstances, there are two measurement principles for coating thickness gauges, which are equipped with F-N probes or FN integrated probes. The oxide layer is generally several micrometers to tens of micrometers, but ordinary coating thickness gauges have relatively large errors and require high-precision coating thickness gauges to measure the oxide layer. For example, Zhongke Pudao's PD-CT2 coating thickness gauge can measure the oxide layer.
The two are only slightly different based on the material, but now many users are not familiar with them and also refer to each other.
How to replace the battery of a coating thickness gauge
The coating thickness gauge can non-destructive measure the thickness of non-magnetic coatings on magnetic metal substrates (such as steel, iron, alloys, and hard magnetic steel) (such as aluminum, chromium, copper, enamel, rubber, paint, etc.) and the thickness of non-conductive coatings on non-magnetic metal substrates (such as copper, aluminum, zinc, tin, etc.) (such as enamel, rubber, paint, plastic, etc.). So, how to replace the battery of the coating thickness gauge? Zhuhai Tianchuang Instrument Company has summarized the following points for everyone:
When the battery voltage is about 2.5V, the battery symbol will appear on the display and the battery needs to be replaced.
2. Open the battery cover and remove the battery.
Install the battery correctly according to the label on the battery box.
If the instrument is not used for a long period of time, please remove the battery to prevent it from rotting and damaging the instrument. The computer is connected according to the label on the battery box, and can communicate with the computer through optional "USB data cable output", "RS232C data cable output", and "Bluetooth data cable output" to achieve functions such as data collection, processing, analysis, and printing. Please refer to the online instructions for specific operations and correctly install the battery.
