DESCRIPTION & TECHNICAL PARAMETERS


DESCRIPTION

The device is used for non-destructive testing of compressive strength in concrete structures such as buildings, bridges, and tunnels.

KEY FEATURES

Laser Detection Module: Contactless and frictionless, with a long service life and higher precision.

2.8-inch touch screen: Diverse input methods, simple interface, and easy operation.

Built-in Bluetooth chip: Connects to the Hichuang mobile app for real-time data upload.

Optional Bluetooth Printer: For on-site printing of original records and test results.

Remote Upgrade Support: Curve synchronization with industry standards and customizable for users.

Dedicated PC Analysis Software: Easy data processing, analysis, and report generation.

Built-in GPRS: Supports cloud data upload. The device comes with a built-in transmission account, ready to use upon startup (only supported by HT-225JC).

Automatic Upload in Signal Coverage: After normal testing in areas without mobile signals, the device automatically uploads data when it is turned on within signal coverage (only supported by HT-225JC).
