TT210 Coating thickness gaugeDetailed product description：

The TT210 coating thickness gauge uses both magnetic and eddy current thickness measurement methods, which can non destructively measure the thickness of non-magnetic coatings (such as zinc, aluminum, chromium, copper, rubber, paint, etc.) on magnetic metal substrates (such as steel, iron, alloys, and hard magnetic steel) and non-conductive coatings (such as rubber, paint, plastic, anodized film, etc.) on non-magnetic metal substrates (such as copper, aluminum, zinc, tin, etc.).
·There are two measurement methods: Continuous measurement method and Single measurement method;
·It has two working modes: direct mode (Direct) and group mode (Appl);
·There are five statistical measures: Mean, Maximum, Minimum, Number of Tests, and Standard Deviation;
·There are two methods to calibrate the instrument, and the basic calibration method can be used to correct the systematic error of the measuring head;
·Storage function: capable of storing 500 measurement values;
·It has a deletion function: it can delete individual suspicious data that appears during measurement, as well as all data in the storage area, in order to conduct new measurements;
·Limits can be set: automatic alarms can be triggered for measurement values outside the limits; And a histogram can be used to analyze a batch of measurement values;
·Printing function: capable of printing measurement values, statistical values, limits, histograms;
·Capable of communicating with a PC: capable of transmitting measured and statistical values to the PC for further data processing;
·Equipped with power undervoltage indication function;
·There is a buzzing sound during the operation process;
·It has an error prompt function, which provides error prompts through screen display or beeping sound;
·There are two shutdown modes: manual shutdown mode and automatic shutdown mode;
