Introduction to LR-H850 Cloud Upload Floor Thickness Detector Instrument
Mainly used for thickness measurement of concrete structures (floor slabs, etc.) or other non-magnetic media. The outstanding feature of this instrument is that within the effective range of signal reception, the receiving probe can automatically find the position of the transmitting probe and lock the center, greatly saving measurement time.

Product Features of LR-H850 Cloud Upload Floor Thickness Detector
1. Applied to Android intelligent system, supporting Android 5.0 and above versions.
2. The intelligent cloud floor thickness detection system software is installed on a handheld device or tablet of the Android system. The detection probe communicates with the handheld device through Bluetooth to achieve real-time transmission of floor thickness detection data.
3. Mobile Internet based on mobile phone or tablet computer platform realizes real-time data collection and self access via devices The camera and GPS positioning system equipped with it can obtain more detection information and better reflect the fairness and reliability of the detection.
4. The system can achieve functions such as data detection, data viewing, parameter setting, and data uploading.
5. LR-H850 cloud uploaded floor thickness detector data detection: It can interact with the detection probe in real time and automatically calculate the effective thickness value. Data viewing: View data that has been saved locally and in the cloud.
6. Parameter settings: You can set the name, design value, detection location, and other information of the detection component, making it more convenient to use with more available information.
7. Data upload: The saved data can be uploaded to the user database in the cloud or exported to the local computer through a data cable.
8. When using the LR-H850 intelligent cloud floor thickness detector for on-site testing, certain testing methods and principles should be followed to ensure more accurate results, otherwise significant deviations may occur.
LR-H850 cloud uploaded floor thickness detector detection precautions:
1. The extension rod is firmly connected to the probe to ensure that the probe will not fall from a high altitude during use, causing damage to the probe.
2. During the testing process, it should be ensured that the surface of the transmitting probe is always in close contact with the testing surface of the tested component (floor, etc.), otherwise the test values will produce errors.
3. During the testing process of the LR-H850 cloud uploaded floor thickness detector, it is necessary to ensure that the instrument and probe have sufficient power, otherwise errors may also occur. If the instrument is low on battery during use, it will sound an alarm (buzzer beeps) and automatically shut down after a period of time. When the probe is low on battery, its power indicator light will flash. At this time, the measurement should be ended to charge the instrument and probe. In addition, if testing is conducted while charging, the test values may also have errors.
4. When testing the LR-H850 cloud uploaded floor thickness detector on site, the measuring points should avoid areas with dense steel bars as much as possible. When the steel bars in the tested component are parallel to the surface of the transmitting probe and on the transmitting probe The closer the steel bar is to the surface of the emitting probe, the greater the impact (the test value is biased). When the steel bars in the tested component are perpendicular to the surface of the emission probe and above the emission probe, the closer the steel bars are to the center of the emission probe, the greater the impact (the test value is relatively small). Experiments have shown that the influence of vertical steel bars is much greater than that of parallel steel bars, so there must be no vertical steel bars at the measurement point position. When the measurement value of a certain measuring point differs significantly from the values of other measuring points (or design thickness values), it may be due to the influence of vertical steel bars, and a different measuring point should be used for testing.
5. When testing the LR-H850 cloud uploaded floor thickness detector on site, the measuring points should be kept as far away from the wires as possible.
6. During on-site testing, the measuring points should be kept as far away as possible from other ferromagnetic media.
7. Avoid using in strong magnetic field environments, such as near large electromagnets, transformers, welding machines, etc.
8. The environmental temperature used for the LR-H850 intelligent cloud floor thickness detector should be between 0 ° C and 40 ° C. If the environmental temperature exceeds this range, there may be errors in the thickness detection value, especially when testing components with a thickness greater than 400mm, where the influence of environmental temperature is significant.
9. When using the LR-H850 cloud uploaded floor thickness detector to measure a certain measuring point, please follow the following steps:
1) Determine the measurement area: During the measurement, the tester holds the host above the tested floor, and another person holds the transmitting probe below the tested floor. The tester notifies the personnel below to support the transmitting probe on the tested floor through a walkie talkie, so that the probe surface is tightly attached to the bottom surface of the floor; Testers will receive probes and floor slabs The upper surface (top surface) is tightly attached, and the receiving probe is moved to the corresponding position of the transmitting probe to observe the change in signal value. When there is a significant change in signal value, it indicates that the receiving probe is within the effective range of the transmitting probe's transmitted signal.
2) Receive the probe The switch on the top points directly in front of the LCD screen. Slowly move the receiving probe within the effective range according to the direction indication on the instrument until the center of the transmitting probe is found. Move the receiving probe several times near the center to ensure the accuracy of the center! The thickness value locked on the instrument after the receiving probe locks the center is the true thickness value of the floor slab!
