PTG-3550使用了一個內置探頭可以自動測量金屬或非金屬基體并且帶有2個標準基體(鋼,鋁)，4個校準過的厚度試片，手提箱，電池和操作手冊。
無損涂層測厚原理 •1) 電磁感應原理:
當在金屬-磁性基體如鋼和鐵上測量涂層的厚度時，菲思圖PTG系列涂層測厚儀使用此無損標準。涂層必須是非磁性的，如:油漆，搪瓷釉，鋁，鉻，銅及黃銅。
當在非磁性基體如鋁，鋁合金，青銅，銅，黃銅，錫黃銅及不銹弱磁性鋼上測量涂層的厚度時，菲思圖PTG系列涂層測厚儀使用此無損標準。涂層必須是電絕緣的，如：油漆，搪瓷釉，塑料制品，電鍍涂層及陶瓷。
注意：所有PTG系列涂層測厚儀都是在發貨之前用兩點校準法檢驗和校準的。
此過程是通過儀器在無涂層的試片上的歸零調整來實現的，您將在此試片上進行涂層厚度的測量。為了完成此校準，您需要遵循操作手冊中的簡易校準方法，它不像使用兩點校準那樣精確。
此過程是通過儀器在我們隨機提供的基體試片(鋼/鋁)上的歸零調整來實現的，然后把其中一個校準過的箔放在基體上并校準儀器以匹配已知箔的厚度。最好使用最接近您的被測試片的實際已知厚度的箔，這是一個非常簡單的過程，在操作手冊中已作說明。經使用兩點校準法，您可以確保儀器在測量您的帶有涂層的試片時是最準確的。在發貨前，我們使用同樣的方法校準每臺儀器。 一旦PTG系列涂層測厚儀被校準后，參數就會被保存而且校準過程不需重復進行。我們建議在長時間操作后或儀器一段時間不使用的情況下，您應該使用與以前校準儀器同樣的校準基體/箔。 |

Nondestructive coating thickness measurement principle
• 1) the principle of electromagnetic induction:
When the metal magnetic matrix such as measurement of coating thickness on steel and iron, the use of thisnondestructive standard phase II PTG series coating thickness tester. The coating must be non-magnetic, such as: paint, enamel, aluminum, chromium, copper and brass.
• 2) eddy current principle:
When the non-magnetic substrate such as aluminum,aluminum alloy, copper, bronze, brass, tin brass and stainless steel measuring coating thickness of weak magnetic steel, the use of this nondestructive standardphase II PTG series coating thickness tester. The coatingmust be electrically insulated, such as: paint, enamel,plastic, coating and ceramic.
The calibration process
Note: all PTG series coating thickness gauge is before shipment by two-point calibration verification and calibration.
• 1 point calibration):
This process is through the instrument in the test piecewith no coating on the zero adjustment to achieve, youwill measure the specimen on the coating thickness. In order to complete the calibration, you need to follow thesimple calibration method in the operating manual, it is not as accurate as using two-point calibration.
• 2) two-point calibration:
This process is the piece of test instrument in the matrixwe provide random (steel / aluminum) on the zero adjustment to achieve, then put one calibrated foil on thesubstrate and the calibration of the instrument to match the known foil thickness. The best use of the known thickness were test piece closest to your foil, this is a very simple process, in the operating manual forinstructions. By using the two-point calibration method,you can ensure that the measurement you with a coatingtest piece is the most accurate. Before shipment, we use the same method for calibration of each instrument.
• 3) calibration frequency:
Once the PTG series coating thickness gauge iscalibrated parameters will be saved, and the calibrationprocess does not need to be repeated. We suggest not to use in a long time after the operation or instrument in a period of time situation, you should use and calibrationmatrix / previously calibrated instruments the same foil.
