MEWOI-KD330 High Precision Surface Roughness Gauge Meter Tester
INTRODUCTION
| MEWOI-KD330 Handheld roughness meter Suitable for cold rolling steel production sites, research laboratories and factory metering rooms.The hand-held roughness meter measures the surface roughness of a variety of machined parts, calculates the corresponding parameters according to the selected measurement conditions, and clearly displays all measurement results and graphics on the LCD display, and can be output on the printer. Communicate with the PC.With value storage and storage data query function. |
MAIN FEATURES
| 1,Appearance using pull aluminum mould design,durable, anti-electromagnetism interference ability significant, accord with current design new trend. | 2,By using high-speed DSP processors for the data processing and calculation, measuring and calculation speed is greatly improved.*Liquid crystal adopts popular OLED display, high brightness, no perspective, wide temperature. It is suitable for various applications |
| 3,Using lithium ion rechargeable batteries, it can work long hours with no memory effect. It also can work with charging .Charging time is short, while the battery life is long. | 4,Use the common USB interface to charge and communication. Use special charger or the computer USB port of charge. It's convenient and quick. |
| 5,Dot matrix LCD display, interface message is rich. | 6,Real-time monitoring of lithium battery power and display, electric charge and timely remind users. |
| 7,Automatic shut down function,low power consumption and hardware design make instrument working hours exceeds. It is suitable for all kinds of field use. | 8,The sensors head has the protect door, which protect the head of the sensors effectively. Guarantee the accuracy of measurement. |
