Surface Roughness Measurement Range

The LANDTEK SRT-6200 measures surface roughness across a range of 0.05 to 10 micrometres Ra and up to 100 micrometres Rz. It is designed for technicians and quality control staff who need to verify the finish of machined parts directly on the production floor. The instrument supports ISO, DIN, ANSI and JIS standards for broad industrial compatibility.

Sustained Operation Behaviour

A built-in lithium-ion rechargeable battery and control circuit provide power for extended measurement sessions without a mains connection. The tester can be set to shut down automatically after a period of inactivity or turned off manually to conserve charge. Data collected during long runs can be streamed to a PC via USB or RS-232, and a Bluetooth output option is also available.

Thermals Noise And Power Draw

The device uses a sophisticated inductance sensor with a sharp probe that slides across the surface, generating an analogue signal proportional to roughness. A dedicated DSP processes this signal and displays results on the LCD with no audible fan or active cooling required. Its compact, lightweight construction keeps power consumption low and ensures quiet operation during normal use.

Questions about this item

Does the SRT-6200 generate noticeable heat or fan noise during extended use on the production floor?

The tester uses a built-in lithium ion rechargeable battery and an inductance sensor with no moving cooling parts, so it runs silently and stays cool during all-day measurement sessions.

What must I already have to power and read data from the SRT-6200?

The unit ships with its own rechargeable battery and control circuit; for data transfer you need a PC with a free USB port or RS-232 interface, or you can use the Bluetooth output option.

Can I connect the SRT-6200 to an older PC that only has a serial port and no USB?

Yes, the tester provides an RS-232 data output alongside USB, so it will communicate directly with legacy serial ports without an adapter.
