TT290 Coating Thickness Gauge (Magnetic Method)
The TT290 coating thickness gauge (magnetic method) is an ultra small measuring instrument that can quickly, non destructively, and accurately measure the thickness of non-magnetic coatings on magnetic metal substrates. It can be widely used in manufacturing, metal processing industry, chemical industry, commercial inspection and other testing fields. The TT290 coating thickness gauge (magnetic method) is particularly suitable for on-site engineering measurements due to its small size and integrated probe and instrument.
The TT290 coating thickness gauge (magnetic method) complies with the following relevant standards:
GB/T 4956-2003 Non magnetic coatings on magnetic substrates - Measurement of coating thickness - Magnetic method
♦ The TT290 coating thickness gauge (magnetic method) can be used for zero point calibration and two-point calibration, and the basic calibration method can be used to correct the systematic errors of the measuring head;
♦ There are two measurement methods: continuous measurement and single measurement;
♦ There are two working modes: direct mode and batch mode;
♦ Store 500 measurement values;
♦ Has deletion function: delete current value, calibration value, limit value, and all values;
♦ There are five statistical measures: Mean (MEAN), Maximum (MAX), Minimum (MIN), Number of Tests (NO.), and Standard Deviation (S.DEV);
♦ Capable of printing measurement and statistical values;
♦ Equipped with undervoltage indication function;
♦ There is a buzzing sound during the operation process;
♦ Equipped with error prompt function;
♦ Chinese and English menus;
♦ Backlight display;
♦ Automatic and manual shutdown.
