Surface Profile Gauge Roughness Tester Ra, Rz, Rq, Rt
ROTE-4451 is one of professional instruments meet all kinds of international standards, such as ISO, DIN, ANSI, JIS. It has four measuring unit Ra, Rz, Rq, Rt ROTE -4451Data transfer to a PC is possible using the devices RS-232 port and optional software
* Be compatible with four standards of ISO, DIN, ANSI and JIS. When measuring the roughness of a surface, the sensor is placed on the surface and then uniformly slides along the surface by driving the mechanism inside the tester. The sensor gets the surface roughness by the sharp built-in probe. This roughness causes displacement of the probe which results in change of inductive amount of induction coils so as to generate analogue signal, which is in proportion to the surface roughness at output end of phase-sensitive rectifier. The exclusive DSP processes and calculates and then outputs the measurement results on LCD.
* Multiple parameter measurement: Ra, Rz, Rq, Rt.
* Highly sophisticated inductance sensor.
* Built-in lithium ion rechargeable battery and control circuit with high capacity.
* Portable, Easy to take and use
*Manual or automatic power off.
* Metric /Imperial Convertible
* Use USB data output with connection PC.
* Bluetooth is Optional
