HT-225K/KC / 225J/JC Digital Rebound Tester

The HT-225K/KC / 225J/JC Digital Rebound Tester is a professional non-destructive testing (NDT) device developed and manufactured by Zhejiang Yiyu Instrument Equipment Co., Ltd. This instrument is primarily used for non-destructive testing of the compressive strength of concrete structures such as buildings, bridges, and tunnels. It combines traditional mechanical rebound testing with modern digital display technology, significantly improving testing efficiency and data accuracy.

Core Functions and Design Highlights

1. Advanced Detection Technology:

• Laser Detection Module (HT-225J/JC only): Utilizes non-contact, frictionless laser detection technology, offering longer service life and higher measurement accuracy.

2. Superior Interactive Experience:

• Equipped with a 2.8-inch touchscreen color display (400×240 pixels), featuring a simple and intuitive interface.
• Supports diverse input methods including touch and button, adapting to different on-site operating habits.

3. Intelligent Data Management:

• Real-time Transmission: Built-in Bluetooth chip allows connection to the "Haichuang" mobile app for real-time upload of bounce data.
• Cloud Interconnection: Built-in GPRS module (HT-225JC/KC only), supporting direct data upload to the cloud, and automatic retransmission when signal is restored after testing in areas without signal.
• Professional Analysis: Equipped with dedicated PC-based analysis software, it automatically corrects, calculates, and statistically analyzes data according to specifications, and quickly generates test reports.

4. User-Friendly Auxiliary Configuration:

• Supports remote upgrades, ensuring curves are synchronized with updated industry standards.
• Optional Bluetooth printer allows for direct printing of original records and test results on-site.

Frequently Asked Questions (FAQ)

Q1: How does this device ensure the authenticity and authority of the data?

A: The system automatically corrects, calculates, and statistically analyzes data according to the latest industry standards, with extremely low consistency error (≤±1), ensuring that the test results meet the specifications.

Q2: Will data be lost when testing in remote areas or areas with poor signal?

A: No (for HT-225JC/KC models). The device will save data when there is no signal. Once it enters a mobile signal coverage area and is powered on, the system will automatically upload the test data.

Q3: Is this instrument easy to operate?

A: Very easy. It has a large 2.8-inch touchscreen and a bilingual (Chinese and English) interface. With simple interactive logic, operators can quickly master the testing process.

Q4: How long is the battery life?

A: The instrument has a built-in high-capacity imported lithium battery of 3200mAh, providing long battery life sufficient for intensive field inspection tasks.

Q5: What are the special advantages of the laser detection module?

A: Compared to traditional contact sensors, the laser detection module achieves frictionless measurement, which not only reduces mechanical wear and extends equipment lifespan but also further improves measurement accuracy.
