Mitech MDW-ZS Electrical Digital Hardness Tester(MDW-ZS6xh,MDW-ZS10xh,MDW-ZS15xh electrical Webster hardness tester
Introduction
MDW-ZJ electrical Webster hardness tester, they are smart designed and can do fast NDT test of workpiece on site. Micro electrical motor can apply the strength, It can do the test by pressing the switch, reduce the labor intensity of testing personnel, it adopts new technology of calibration without dismantle and indenter protection device, improve the accuracy. Digital display can make you read more clear. It is the best choice of testing batch products and been widely used in each process of aluminum production test, acceptance inspection and products quality inspection, as well as in engineering quality inspection and technical supervision departments.
Operating Method and Attentions
Operation
The tester has security lock to avoid misoperation, before measurement, press the switch for 1s, until indicator turns red to start measuring.
① Put the workpiece between anvil and pre pressing device, with a beep the reading will show the
Hardness.In order to ensure the accuracy of the measurement results and not to destroy the compression device and needle ,user need to keep the measured stable;
② Release switch, the needle will back to initial position
Notes:
Press the trigger when the left light turns red, indenter goes on, right light turns blue, when the indenter stop, blue indicator goes out. Release the switch the indenter go up, right side light turn red, when the indenter stop, red indicator goes out. 20s later, power auto-off, left red indicator goes out.

Instrument Maintenance
- Prevent contamination, use soft cloth to clean the dust or stain of the tester especially remove the contamination on the dial head or it will cause error.
- Prevent rust, when using pay special attention to its waterproof performance except clean it frequently, many parts will bear rust with water, the rust in the dial head will cause the instrument useless.
- Prevent falling off, the tester is made up of many precision components, falling off will result in permanent damage to some parts.
- Do not dismantle, all the components had already been put together properly in factory except calibration.
- If the instrument is not used for a long time, user should remove the battery in time to prevent the battery leak which may shorten the service life.
