L&W Bendtsen Tester enables accurate checking of roughness specifications that comply with standard methods. The automatic alignment of the measuring head with samples, and the preset measuring time ensure correct results. The compact design effectively protects the measuring head and the glass surface. As L&W Bendtsen Tester is a totally integrated instrument, there are no loose parts that can jeopardize the reliability or repeatability when measuring roughness and compressibility.

Operator-friendly

L&W Bendtsen Tester is designed to be as convenient as possible to use. Once the measuring sequence is set all the operator needs to do is place the paper sample in the measuring gap. A sensor detects the paper and the measuring process starts. The sample is automatically raised against the measuring head so that it rests against the paper sample with a constant standard contact pressure of 98 kPa. The sample is then released and can be moved to another position until all measurements are completed. The automatic measuring process prevents handling errors.

The results are shown on a digital display and printed out on the built-in printer. Results can also be sent to a laboratory computer via the signal output.
