PCE-RT1200 Roughness tester
portable meter for the fast detection of roughness (Ra, Rz, Rq y Rt)
with large display and RS-232 port

The PCE-RT1200 roughness tester meets all the expectations to detect the surface roughness. With the PCE-RT1200 roughness tester you can analyze different material surfaces. The PCE-RT1200 roughness tester can measure up to 4 different roughness parameters and transfer these data to a PC ( via the optional software). This is recommended if the PCE-RT1200 roughness tester is used for series measurements in order to control the entry of goods from suppliers, or to determine the quality control of the products at the laboratory. The PCE-RT1200 roughness tester will be delivered with a calibrated. Additionally, you can order a laboratory calibration and an ISO certificate (at extra cost). At the following link you will find an overview of roughness testers available at PCE-Instruments.

The ergonomic PCE-RT1200 roughness tester with interface has the following characteristics:
- compact design
- easy-to-use
- large LCD display
- 4 parameters to measure roughness
- indication of the probe pointer position
- auto shut-off after 5 minutes without pressing any key (with basic automatic
memory)
- RS-232 port for online data transmission to a PC (e.g. for series measurements at the
laboratory)
- Rechargeable internal accumulator (3000 measurements with an [Ion-Lithium] charge)

Rz: average depth roughness
The depth of average roughness Rz is the arithmetic average of the lowest roughness depth of different adjacent measuring sections.

Ra: arithmetic average of the absolute values
Ra is a roughness parameter used worldwide. It is the arithmetic value of absolutes values of the profile variations within the measuring section. The measured numerical value is always lower than the Rz obtained in the same profile roughness.

- Software kit
The software allows to transfer data directly to a PC or portable computer. Data can also be sent to other programs for further analysis. Data can be represented in diagrams or in columns. This allows to analyzed and document measurement values.

- USB-RS232 Adapter
If you wish to use the PCE-RT1200 roughness tester for measurements at the working place or if you wish to transfer data to a portable computer, a RS-232 / USB converter is required.
