PTG-3550使用了一個(gè)內(nèi)置探頭可以自動(dòng)測(cè)量金屬或非金屬基體并且?guī)в?個(gè)標(biāo)準(zhǔn)基體(鋼,鋁)，4個(gè)校準(zhǔn)過的厚度試片，手提箱，電池和操作手冊(cè)。
無損涂層測(cè)厚原理 •1) 電磁感應(yīng)原理:
當(dāng)在金屬-磁性基體如鋼和鐵上測(cè)量涂層的厚度時(shí)，菲思圖PTG系列涂層測(cè)厚儀使用此無損標(biāo)準(zhǔn)。涂層必須是非磁性的，如:油漆，搪瓷釉，鋁，鉻，銅及黃銅。
當(dāng)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(cè)量涂層的厚度時(shí)，菲思圖PTG系列涂層測(cè)厚儀使用此無損標(biāo)準(zhǔn)。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(cè)厚儀都是在發(fā)貨之前用兩點(diǎn)校準(zhǔn)法檢驗(yàn)和校準(zhǔn)的。
此過程是通過儀器在無涂層的試片上的歸零調(diào)整來實(shí)現(xiàn)的，您將在此試片上進(jìn)行涂層厚度的測(cè)量。為了完成此校準(zhǔn)，您需要遵循操作手冊(cè)中的簡(jiǎn)易校準(zhǔn)方法，它不像使用兩點(diǎn)校準(zhǔn)那樣精確。
此過程是通過儀器在我們隨機(jī)提供的基體試片(鋼/鋁)上的歸零調(diào)整來實(shí)現(xiàn)的，然后把其中一個(gè)校準(zhǔn)過的箔放在基體上并校準(zhǔn)儀器以匹配已知箔的厚度。最好使用最接近您的被測(cè)試片的實(shí)際已知厚度的箔，這是一個(gè)非常簡(jiǎn)單的過程，在操作手冊(cè)中已作說明。經(jīng)使用兩點(diǎn)校準(zhǔn)法，您可以確保儀器在測(cè)量您的帶有涂層的試片時(shí)是最準(zhǔn)確的。在發(fā)貨前，我們使用同樣的方法校準(zhǔn)每臺(tái)儀器。 一旦PTG系列涂層測(cè)厚儀被校準(zhǔn)后，參數(shù)就會(huì)被保存而且校準(zhǔn)過程不需重復(fù)進(jìn)行。我們建議在長(zhǎng)時(shí)間操作后或儀器一段時(shí)間不使用的情況下，您應(yīng)該使用與以前校準(zhǔn)儀器同樣的校準(zhǔn)基體/箔。 |

PTG-3550 coating thickness tester PTG3550
With this advanced thickness measuring instrument,using a built-in probe or we provide an automaticdetection of the external probe, you can measure themagnetic matrix convenient (metal) on the non magnetic coatings thickness or non magnetic conductive substrate(non-metallic) non conductive coating thickness.
Phase II PTG-3550 can be used in many industriesincluding manufacturing, general machinery industry,commodity inspection, etc..

PTG-3550 uses a built-in probe can be automatically measured metal or non metal matrix and with 2 standardmatrix (steel, aluminum), 4 calibrated thickness specimen,suitcase, battery and operation manual.
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.
