Overview
RJJD220 Portable Roughness Gauge is a new generation of pocket Portable surface roughness instrument launched by RUNJIE. It has the characteristics of high Measurement accuracy, wide Measurement range, easy operation, easy to carry, stable work, etc., and can be widely used in the detection of various metal and Non-metallic machined surfaces. The instrument is a pocket instrument integrated with the Sensor host, with Handheld characteristics, which is more suitable for use in production sites.
Features
1. Using optimized circuit design and Sensor structure design, the electric box, driver and display part are integrated to achieve a high degree of integration
2. Ra, Rz, Rq, Rt Measurement parameters can be arbitrarily selected
3. Not only can measure the outer circle, plane and cone, but also the groove with length and width greater than 80 × 30mm
4. The shape is designed with a drawn aluminum die, which is sturdy and durable, and has significant resistance to electromagnetic interference
5. High-speed DSP processor for data processing and calculation, measurement and operation speed is greatly improved

7. Using lithium ion rechargeable battery, can work for a long time, no Memory effecy, can work while charging
8. Use a universal USB port for charging and communication
9. point matrix LCD display, interface prompts rich information
10. Real-time monitoring of lithium battery power and display, with charging progress prompts
11. Automatic shutdown function and low power consumption hardware and software design make the instrument Working time super long
12. Sensor probe with protective door, effectively protect Sensor probe, ensure Measurement accuracy
Principle
The Portable Roughness Gauge uses a high-speed DSP processor for data processing and calculation. Sensors measure surface roughness parameters and display the measurement results on the OLED color display.
Applications
Machined surface inspection of various metals and Non-metallic
Steps
1. Turn on the instrument power
2. Select the parameters to be measured (Ra, Rz, Rq, Rt)
3. Align Sensor Probe to Surface
4. Perform measurement operations
5. Read the measurement results on the display
Notice
• Operating Conditions: Temperature -20 ℃~ 40 ℃; relative humidity < 90%; no vibration around, no corrosion medium
• Protect Sensor Probes to Avoid Collision and Damage
• Monitor battery power in time and charge it
• Make sure that the static force of the Sensor stylus is less than or equal to 0.016N when using
• Ensure Sensor Guide Pressure ≤ 0.5N when using
• Avoid using the instrument under conditions beyond the specified environment
