Coating Thickness Gauge

La description

â… .Features of instrument:
MC****0C coating thickness gauge is the fruit of high technology. It applies to the single chip microcomputer technology. It has high precision, digital display, stable indication and low power consumption. It can be easily operated and the keys should be pressed by touch. With a small volume and light weight, it provides sing probe full range measurement. It also has such functions as storing, reading, statistic, low-power indication, system/zero-scale/two-point calibration. Its properties have reached the international advanced levels of contemporary instruments of the same kind.
â…¡.Application scope:
This instrument applies to the magnetic thickness gauging method. It can measure the thickness of non-magnetic coating on ferromagnetic materials conveniently and without any damage. For example, it can measure the thickness of the zinc, copper, chromium, paint, enamel, fiberglass, sprayed plastic, asphalt.etc. on the surface of steel. This instrument is widely applied in mechanical, car, shipbuilding, petroleum, chemical, electroplating, spray plastic, enamel, plastic etc. industries.
Ⅲ．Working principles:
NJC****0C coating thickness gauge applies to electromagnetic induction method. The probe located on the surface of the instrument can produce a closed magnetic loop. With the change of the distance between the probe and the ferromagnetic material, the magnetic loop will change to different degrees and so the magnetoresistance and probe coil inductance change. With this principle, it can accurately measure the distance between the probe and the ferromagnetic material, that is, the thickness of the coating.
Ⅳ．Techonoligical parameters:
1.measurement scope: 0~***0um

   (2)storage and deletion: it can store **0 measured data, delete some suspicious data and delete all the data that have been stored.
(3)reading: it can read the measured data that have been stored.
 (4)statictic: there are three statistical values—the average value, the maximum value and the minimum value
(5)calibration: zero-scale calibration, two-point calibration and system calibration
(6)electric quantity: it has the function of displaying low power
(7)buzz indication: there is buzz indication in operation
(8)print: with a micro-printer it can print the measured data
(9)powering off: there are two means of powering off—automatic powering off and manual powering off
