Overview
The KAIRDA NDT110 surface roughness instrument is a pocket surface roughness instrument with a drawn aluminum die design and conforms to GB/T 3505-2000 and GB/T 6062-2002 standards. The instrument is suitable for detecting the surface roughness of metal and Non-metallic parts under test. After strict temperature and Humidity tests, it can be measured in high temperature and high Humidity environment. Measurement parameters of Ra, Rz, Rt and Rq are supported.
Features
1. Adjustment, simple and convenient operation
2. 4 kinds of Measurement parameters Ra, Rz, Rt, Rq can be selected
3. Optical inspection Glass matrix for calibrated samples, identified by the National Institute of Measurement, high accuracy, not easy to scratch, long service life
4. High-speed DSP processor for data processing and calculation, fast speed, higher accuracy
5. There are two charging methods: a special charger or a computer USB interface, which can work while charging, which is fast and convenient
6. With automatic shutdown function and low power consumption software and hardware design, Working time is long
7. Adopt aluminum die design shape, sturdy and durable, with anti-electromagnetic interference ability
8. Sensor probe has a protective door, which can effectively protect Sensor probe and ensure Measurement accuracy
9. point array LED LCD screen, high luminance, no viewing angle, wide temperature, suitable for various occasions
10. Three sampling lengths of 0.25, 0.80 and 2.50 can be selected
Principle
The Roughness Gauge adopts contact (stylus) Measurement principle, and collects contour data by moving the sensor probe on the surface of the workpiece, and uses a high-speed DSP processor for data processing and calculation to obtain surface roughness parameters.
Applications
Metal and Non-metallic parts to be tested surface roughness detection, a variety of machined parts, machining manufacturing, testing, commodity inspection and other departments, large workpieces and production lines of on-site inspection, testing, Measurement, commodity inspection and other departments of verification, measurement plane, diameter greater than 20mm outer circle, cone, length and width greater than 80 × 30mm groove
Standards
GB/T 3505-2000、GB/T 6062-2002
Steps
1. Power on the instrument
2. Measurement parameters (Ra, Rz, Rt, Rq) and sampling lengths (0.25mm, 0.8mm, 2.5mm) are selected as required
3. Align the Sensor probe with the measured surface to ensure the normal operation of the protective door
4. Start the measurement, the instrument automatically collects data and calculates
5. Read the measurement results through the point matrix LED LCD screen
6. After the measurement is completed, you can connect the USB interface for data transmission or charging
7. Use the automatic shutdown function or manually turn off the power
Notice
• Ensure that the working Ambient Temperature is in the range of -20 ℃~ 60 ℃, and the relative humidity is less than 90%
• There should be no vibration and no corrosion medium around
• Sensor guide pressure should be ≤ 0.5N to avoid damage to the workpiece
• Regularly calibrate samples to ensure Measurement accuracy
• Special charger or computer USB interface can be used when charging, pay attention to safe operation
• Sensor probe protection door should be kept clean to prevent damage
• When measuring the outer circle, the diameter should be greater than 20mm; when measuring the groove, the length and width should be greater than 80 × 30mm
