Frequently Asked Questions (FAQ)
Q1: What is the practical use of the "secondary display" on the HC-GY81S?
A: Its 1.54-inch synchronous display is primarily designed for testing at heights or in hazardous locations. Operators can secure the main unit at the test site and remotely view data or control the device via the secondary display, eliminating the need for frequent climbing and enhancing safety.
Q2: How does it perform in environments with densely spaced rebar?
A: The device features an optimized detection algorithm for waveform scanning modes, significantly improving its ability to identify densely spaced rebar and ensuring more accurate concrete cover thickness readings.
Q3: Can I view testing data in real-time on my mobile phone?
A: Yes. By connecting to the mobile app via the built-in Bluetooth 5.2 chip, testing data can be uploaded and displayed synchronously within seconds.
Q4: Is the battery durable? How long does a single charge last?
A: The device utilizes a high-capacity 18650 lithium battery combined with a low-power design. A full charge allows for over 24 hours of continuous operation, sufficient for intensive on-site testing tasks.
Q5: How does the laser indicator assist with positioning?
A: Once activated, the four-way laser projects the precise location of the rebar and the centerlines of adjacent bars onto the structural surface. Before drilling or coring, this effectively prevents accidental rebar cutting, thereby safeguarding the structural integrity of the building.
