TT220 Coating Thickness Gauge This instrument is an ultra-compact gauge that can quickly and accurately measure the thickness of non-magnetic overlays on magnetic metal substrates. This instrument conforms to the following standards: GB/T4956-1985 Measurement of non-magnetic covering thickness on magnetic metal substrate Magnetic method JB/T8393-1996 Magnetic and eddy current cladding thickness measuring instrument JJG889-95 "Magnetoresistive Thickness Gauge"
★ This instrument adopts two thickness measurement methods, magnetic and eddy current, which can non-destructively measure the thickness of the non-magnetic covering layer (such as zinc, aluminum, chromium, copper, rubber, paint, etc.) on the magnetic metal matrix (such as steel, iron, alloy and hard magnetic steel, etc.)
★ Zero-point calibration and two-point calibration can be carried out, and the systematic error of the probe can be corrected by the basic calibration method;
★ There are two measurement methods: continuous measurement method (CONTINUE) and single measurement method (SINGLE);
★ There are two ways of working: direct (DIRECT) and grouped (Appl)
★ It has the function of deleting: it can delete a single suspicious data that appears in the measurement, and can also delete all the data in the storage area in order to make a new measurement;
★ There are five statistics: mean (MEAN), maximum (MAX), minimum (MIN), number of tests (NO.), standard deviation (S.DEV);
★ It has the function of converting meters and imperial systems;
★ It has the function of under-Voltage indication;
★ There is a beep prompt during the operation;
★ It has the function of error prompt;
★ It has an automatic shutdown function.
It can be widely used in manufacturing, metal processing industry, chemical industry, commodity inspection and other testing fields. Due to the small size of the instrument and the integration of the probe and the instrument, it is particularly suitable for on-site measurements.
