Surface roughness meter HR3100

Portable roughness meter HR3100 is a new generation of pocket portable surface roughness meter launched by our company. It has the characteristics of high measurement accuracy, wide measurement range, simple operation, easy portability, stable work, etc. It can be widely used in the detection of processed surfaces of various metals and non-metals. This instrument is a pocket-sized instrument integrated with sensor host, with handheld features, and is more suitable for productionUse on site.

advantage:

Using optimized circuit design and sensor structure design, the electrical box, driver and display part are integrated to achieve high integration; the Ra, Rz, Rq, and Rt measurement parameters are selected at will; not only can the outer circle, plane, and conical surface be measured, but the grooves with a length and width greater than 80×30mm can be measured.

Functional Features:

The appearance is designed with pull-aluminum mold, which is strong and durable, and has significant anti-electromagnetic interference capabilities, which is in line with today's new design trends.

The data processing and calculation are used for high-speed DSP processor, and the measurement and computing speed is greatly improved.

The display LCD uses a popular OLED color display with high brightness, no viewing angle and wide temperature, which is suitable for use in various occasions.

It uses lithium-ion rechargeable batteries, which can work for a long time without memory effect, can work while charging, short charging time and long battery life.

Use a common USB interface for charging and communication. It uses a dedicated charger or computer USB port to charge, which is convenient and fast.

Dot matrix LCD display, rich interface prompt information.

Monitor the lithium battery power in real time and display it, promptly remind users to charge and have charging progress prompts.

The automatic shutdown function and low-power hardware and software design make the instrument work for a very long time and are suitable for all kinds of on-site use.

The sensor probe has a protective door, which effectively protects the sensor probe and ensures the measurement accuracy.
