The XH-CZ-400 pocket surface roughness meter is a new intelligent instrument used to measure the surface roughness of machined parts. This instrument integrates current microprocessor technology and sensing technology, and is designed with microprocessors and integrated circuits to form an ultra small architecture that adapts to the current trend of instrument development. It can complete the collection, processing, and display of roughness parameters. Applicable to departments such as processing industry, manufacturing industry, testing, and commercial inspection, suitable for on-site inspection of large workpieces and production lines, as well as external inspection by departments such as testing, measurement, and commercial inspection. Not only can it measure outer circles, planes, and conical surfaces, but it can also measure grooves with a length and width greater than 80 x 30mm.

Dot matrix LCD display with rich interface prompts.
Real time monitoring of lithium battery level and display, timely reminding users to charge and with charging progress prompts.
The automatic shutdown function and low-power software and hardware design make the instrument work for an extended period of time, making it suitable for various on-site uses.
The sensor probe has a protective door, which protects the sensor probe and ensures measurement accuracy.
Applicable materials
Suitable for departments such as processing industry, manufacturing industry, testing, and commercial inspection, it is mainly suitable for on-site inspection of large workpieces and production lines, as well as external inspection by departments such as testing, measurement, and commercial inspection.
Basic Principles
When the sensor moves uniformly in a straight line along the measured surface under the drive of the driving mechanism, the internal contact pins perpendicular to the working surface produce vertical displacement with the micro uneven contour of the working surface. The displacement change is then converted into a change in electrical quantity through the sensor, and the electrical signal is amplified, filtered, converted into a digital signal through A/D, and then processed by DSP to calculate the values of Ra, Rz, Rq, and Rt and displayed.
