Surface Roughness Tester ART100 model

General Introduction

AJR ART100 model is a new portable Surface Roughness Tester developed by our AJR NDT company. Featuring high accuracy, wide range of application, simpleoperation and stable performance. It is widely applicable in testing surfaces of all kinds of metals and non-metals. Integrating pick up with the main unit, it is a hand-held set, especially suitable for use on production sites. ART100 confirms to NIST calibration requirement, also DIN 4768 and ISO 4288.

Features

Aluminum mould design, durable, anti-electromagnetism interference case.

By using high-speed DSP processors for the data processing and calculation, measurement just take several seconds.

Liquid crystal adopts popular OLED display, high brightness, no perspective. It is suitable for various applications.

With rechargeable lithium batteries, it can work long hours with no memory effect. It also can work while charging.

The machine is charged by USB interface.

Dot matrix LCD display, interface message is rich.

Real-time monitoring of lithium battery power and display, electric charge and timely remind users.

Automatic shutdown function,low power consumption and hardware design make instrument working hours exceeds. It is suitable for all kinds of field use.

The sensors head has the protect door,which protect the head of the sensors effectively. Guarantee the accuracy of measurement.

Work Principle

When the pickup driven by a driver is making a linear uniform motion along the test surface,the contact stylus in perpendicular with the work surface is moving up and down on the work surface. Its motion is converted into electric signals, which are amplified, filtered and transformed into digital signals through A/D. The signals are then processed by the DSP into Ra and Rz values before displayed on the screen.
