High-efficiency changeable probes with integrated printer to print on site compared with Ultrasonic Hardness Tester

Introduction

Wide measuring range. Based on the principle of Leeb hardness testing theory. It can measure the Leeb hardness of all metallic materials.

Large screen(128×64 dot matrix LCD), showing all functions and parameters.

Test at any angle, even upside down.

Direct display of hardness scales HRB, HRC, HRA, HV, HB, HS, HL.

Seven impact devices are available for special application. Automatically identify the type of impact devices.

Large capacity memory could store 500 groups (Relative to average times32～1 ) information including single measured value, mean value, testing date, impact direction, impact times, material and hardness scale etc.

Upper and lower limit can be preset. It will alarm automatically when the result value exceeding the limit.

Battery information indicates the rest capacity of the battery and the charge status.

User calibration function.

Software to connect with PC via USB port.

With EL background light.

Thermal printer integrated, convenient for in field printing.

NI-MH rechargeable battery as the power source. Charge circuit integrated inside the instrument.

Operating Method and Attentions

1 Start-Up

----Insert the plug of the impact device into the socket of impact device on the instrument.

----Press the power key,now power is on. The instrument is in working mode.

2 Loading

Pushing the loading-tube downwards until contact is felt. Then allow it to slowly return to the starting position or using other method locking the impact body.

3 Localization

Press the impact device supporting ring firmly on the surface of the sample, the impact direction should be vertical to the testing surface.

4 Testing

Press the release button on the upside of the impact device to test. The sample and the impact device as well as the operator are all required to be stable now. The action direction should pass the axis of the impact device.

Working Conditions

• Working temperature: -10℃～＋50℃;
• Storage temperature:-30℃～＋60℃;
• Relative humidity: ≤90％;
• The surrounding environment should avoid of vibration, strong magnetic field, corrosive medium and heavy dust.

Safety Instructions

• The instrument can only work with the specially designed battery pack and power adapter (charger) supplied by Mitech Co. LTD. Working with others may result in damage of the instrument, battery leakage, fire or even explosion.
• Do not cast the battery pack into fire and do not short circuit, disassemble or heat the battery pack, otherwise battery leakage, fire or even explosion may occur.
• Do not open the cover of the paper compartment or come into contact with the heating head of the printer by hand or any part of your body to avoid burns due to high temperature when the printer is printing.
