HC-200 Series Digital Thickness Gauges

 HC series of coating thickness gauge is a portable thickness gauge with eddy current thickness method and electromagnetic thickness method. It can be used to quickly and accurately measure the thickness of coating or cladding material without damaging it. As an  essential instrument for professional material protection,this coating thickness gauge is widely used in manufacturing industry, metal processing industry, chemical industry and commodities inspection etc.,both in the laboratory and in the engineering field. It can measure the thickness of nonmagnetic layer on magnetic metal substrate condition (such as steel, iron, alloy and hard magnetic steel, etc.) and the thickness of conductive layer on nonmagnetic metal substrate condition (such as rubber, paint, plastic, anodic oxidation film, etc.).            


 Main Characteristics:                        


1.  With both the magnetic and eddy current thickness method, as well as measuring the thickness of the magnetic non-magnetic coating on metal substrates can measure the non-magnetic again the thickness of the conductive coating on metal substrates;

2.  Two measuring methods: CONTINUE and SINGLE;

3.  Two working modes: direct mode and burst mode;

4.  With five statistics:MEAN,MAX,MIN,NOS.DEV;

5.  Two methods can be used together for calibration, basic calibration method and can be used to modify the system error of  measuring head;

6.  With functions of storage:in storage 500 observed value;

7.  Delete function: can delete the single suspicious measurement or the all storage data in order to start a new measurement;

8.  To set boundaries:the measured value beyond the limit alarm automatically; And can be used histogram analysis of a batch of measurements;

9.   Have print function: can print measurement, statistics, limit, histogram;

10. Can be communicated with a PC: Measurements, statistical values can be transmitted to the PC, so that the data can be further processed;

11. With low supply voltage indication function;

12. Operation works with beep prompt;

13. Has the error function, through onscreen or beep error message;

14. There are two shutdown modes: manual shutdown mode and automatic shutdown mode

15. Dimension147×65×30mm

16. Weight0.2kg
