Overview
The AMITTARI AR-132CT concrete surface texture tester is a Portable asperity measuring instrument widely used on construction sites for measuring concrete surface roughness, calculating parameters according to selected conditions and displaying them clearly on LCD monitors. The instrument uses computer technology and complies with several international standards.
Features
1. Multi-Parameter measurement: Support Ra, Rz, Rq, Rt parameters.
2. High Accuracy Inductance Sensor.
3. Four filtering methods: RC, PC-RC, GAUSS, D-P.
4. Built-in high-capacity lithium-ion rechargeable battery and charging control circuit.
5. Mechatronics design, small size, light weight, easy to use.
6. With automatic shutdown function.
7. Memory 7 sets of measurement data and conditions.
8. Metric to British conversion function.
9. Use USB data cable output to communicate with PC.
10. Provide Bluetooth data output selection.
Principle
During measurement, the Sensor is placed on the surface of the workpiece to be measured, and the internal driving mechanism drives the Sensor to slide at constant speed. The Sensor has a built-in sharp stylus to feel the surface roughness. The displacement of the stylus changes the Inductance of the Sensor Inductance coil, and generates an analog signal proportional to the asperity at the output of the phase-sensitive rectifier. The signal is amplified and level converted into the data collection system. The DSP chip performs digital filtering and parameter calculation. The results are displayed on the liquid crystal display and can be connected to the PC for Data analysis and printing.
Applications
