Surface Roughness Tester ART100 model
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
Aluminum mould design, durable, anti-electromagnetism interference
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.
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.
