Product Overview
MITECH MR100 pocket surface roughness tester instrument, based on the principle of needle drawing method, with advanced sensor systems and DSP technology, it can detect the mental surface roughness accurately and sensitively. And it’s the latest product. High precision, easy to carry, stable and reliable, it is widely used in a variety of metal and non-metallic surface roughness detection. It’s a necessary products that improve production efficiency, reduce the cost of production.
Function & application
l a variety of machined parts of the roughness detection;
l l all kinds of metal and non-metallic processing surface detection;
l l detection, measurement, commodity inspection and other departments sampling;
l l large parts and production lines roughness quality control links.
Working PrincipleNeedle scanning method, start the instrument and do the measurement after placing the instrument on the surface of the work-piece. The inside precision driven component of instrument drive the probe slide straightly along the surface of the workpiece while the probe with its sharp stylus detecting the surface of the workpiece. At the same time the workpeice surface roughness will make the stylus displacement along vertically. This displacement makes the probe piezoelectric wafer deform and output electric signal. After amplified and level translated, this signal will go to the data acquisition system.DSP chip will conduct digital filtering and parameter calculation for the collected data. And the measurement results will be displayed on the OLED display screen.

l Widely used in a variety of metal and non-metallic surface roughness detection
l Set the sensor probe protection door, after the end of the measurement should be closed to protect the door to.effectively protect the sensor probe;
l Meet the relevant standards at home and abroad;
l Can manually select the sampling length.
Operating Method and Attentions① When the probe is moving, make it as steady as possible to avoid affecting the
measurement precision.
② The instrument will not do response to any measure operation before the probe back to
the original place. It only can permit new measurement until completing the last measurement .
Instrument Maintenance① Avoid collisions, severe vibration, heavy dust, moisture, oil, strong magnetic field and so on.
② After each measurement completed, please turn off the power in time to preserve battery power and the battery should be charged in time.
③ 3 hours’ charging is best for the instrument. To prevent battery damage, you should not overcharge.
④ The probe is one of the most precise components to be used carefully. Please close the probe protect door softly after using to avoid probe damage caused by vibration.
⑤ The standard model should be carefully protected to avoid precision lose caused by scratch. Please package the model in time after measuring.
