1.Features:
This instrument is compatible with four standards of site to measure surface roughness of various machinery-processed parts, calculate corresponding and clearly display all measurement parameters.
When measuring the roughness of a surface, the sensor is placed on the surface and then uniformly slides along the surface by driving the mechanism by the sharp built-in probe. This roughness causes displacement of the probe which results in change of inductive amount of induction coils so as to generate
analogue signal, which is in proportion to the surface roughness at output end of phase-sensitive rectifier. The exclusive DSP processes and calculates and then
outputs the measurement results on LCD.
* Multiple parameter measurement: Ra, Rz, Rq, Rt
* Highly sophisticated inductance sensor
* Four wave filtering methods : RC, PC-RC, GAUSS and D-P
* Built-in lithium ion rechargeable battery and control circuit with high capacity
* Small in size, light in weight and easy to use
* Can communicate with PC computer for statistics, printing and analyzing by the optional cable and the
software for RS232C interface.
*Manual or automatic shut down. The tester can be switched off by pressing the Power key at any time.
On the other hand, the tester will power itself off about 5 minutes after the last key operation.
*The tester can memorize 7 groups of measurement results and measuring conditions for later use or download to PC.
*Metric /Imperial Conversion

Mill scale, is formed on the outer surfaces of plates, sheets or profiles when they are being produced by rolling hot iron or steel billets in rolling or steel mills.
It looks like a hard brittle sand and is mainly composed of iron oxides, mostly ferric, and is bluish black in color.
Being produced during the reheating, conditioning and hot rolling operation for the production of steel articles, the mill scale initially adheres to the steel surface and protects it from atmospheric corrosion, provided no break occurs in this coating.
From the chemical and physical analysis performed on the scrap, and according to the european environmental rules, the material has been classified as a special non dangerous waste, listed in green list
In particular the mill scale can be classified as follows:
Einecs (european commission no.): 266-007-8
Waste code: 10 02 10
Basel code: b 12 30
Hs code: 2619.00
