Product Overview
The RJ200 concrete coating thickness gauge is a portable device based on the principle of non-destructive ultrasonic measurement. It employs a high-speed processor, high-precision metering chip, and high-frequency precision monocrystalline probe to quickly and accurately measure the thickness of paint coatings on concrete or cement surfaces, as well as floor paint thickness. This instrument is lightweight and designed for on-site inspection use.
Product Features
1. Equipped with a high-frequency single crystal probe for stable and reliable measurements.
2. Features a high-precision timing chip with automatic real-time calibration for accurate measurement.
3. Supports both layered measurement and total thickness measurement.
4. Uses a 2.3-inch color screen with high display resolution.
5. Handheld design, easy to carry, suitable for on-site testing.
6. Automatically adjusts signal gain for automatic recognition of thick and thin materials.
7. Available in bilingual versions (Chinese and English).
8. Offers both manual and automatic shutdown modes for user flexibility.
9. Built-in sound velocity data for various common materials, which can be edited for user convenience.
10. Provides sound velocity calibration and sound velocity calculation functions.
11. User-friendly data storage mode: large-capacity storage, supports grouped data storage, with up to 10 groups, each storing 200 data points, for a total of 2000 data points.
12. Large storage capacity, supports viewing and deletion operations, simple and convenient.
Working Principle
This instrument uses ultrasonic measurement principles, emitting ultrasonic waves through a high-frequency precision single-crystal probe. The ultrasonic waves propagate through the concrete coating and reflect back to the probe. The processor measures the propagation time of the ultrasonic waves in the coating based on high-speed computation and a high-precision timing chip, and calculates the coating thickness using the known sound velocity. The instrument features an automatic calibration function to ensure measurement accuracy and stability.
Application Areas
Measurement of paint coating thickness on concrete surfaces, measurement of floor paint thickness
Operation Steps
1. Turn on the device and select the measurement mode (layered or total thickness).
2. Perform velocity calibration or select a built-in velocity setting.
3. Place the probe flat on the surface of the coating under test, applying appropriate pressure.
4. Observe the screen display and record the measurement results.
5. Save data as needed (can be stored in groups, with a maximum of 200 data points per group).
6. After completing the measurement, choose to power off manually or automatically.
Precautions
- Ensure the probe is in close contact with the coating surface before use to avoid gaps affecting measurement
- Perform regular sound velocity calibration to maintain measurement accuracy
- Avoid using the instrument in extreme temperature or humidity environments
- Group and manage data carefully during storage to prevent accidental deletion
- Choose manual or automatic shutdown based on user preference; when not in use for extended periods, manual shutdown is recommended to save battery
