Surface Roughness Tester ART100 model
AJR ART100 model is a new portable Surface Roughness Tester
developed by our 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.
◆Appearance using pull aluminum mould design,
durable,anti-electromagnetism interference ability significant,
accord with current design new trend.
◆ By using high-speed DSP processors for the data processing and
calculation, measuring and calculation speed is greatly improved.
◆Liquid crystal adopts popular OLEDdisplay, high brightness,no
perspective,wide temperature. It is suitable for various
◆ 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.
◆ Use the common USB interface to charge and communication. Use
special charger or the computer USB port of chargeIt's convenient
◆ 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.
