Defelsko The PosiTector RTR P3 is an advanced digital surface roughness meter, a high-end surface profile gauge that measures both peak height and density, and is capable of outputting 2D/3D images as well as high-resolution SDF files for 3D graphical analysis of the surface of the material being measured.PosiTector RTR P3The measured peak height value of the digital surface roughness meter is 20~115μm, and the accuracy is ±5μm.





RTR P3 Digital Surface Roughness TesterIn addition to the general features of the PosiTector RTR series, the following benefits include:
1. High-resolution color LCD screen
2. Up to 100,000 measurement readings are stored, 1,000 batches
3. The peak height and peak density can be measured at the same time
4. Able to display 2D/3D pictures and output high-resolution SDF files
5. WiFi technology, wireless connection to PosiSoft, download software updates and connect to wireless devices to expand functions
6. Bluetooth wireless technology transmits data to the computer
7. Real-time graphics, picture prompts and batch display
